The price of gas may go up or down, but it's always a major expense for most drivers. The average American driver spends about $3,000 per year on gas, according to the American Automobile Association. Some of the practical ways to reduce fuel costs are listed below.

Use public transportation

Walking or biking does not consume fuel, and as such does not accumulate fuel cost. In most cases, public transport alternatives to cars such as buses, trains, and trolleys are viable options of reducing fuel costs. Due to the communal nature of ride sharing, the fuel costs of operating public transport are generally less than the fuel costs associated with each individual operating their own vehicle. In some places, public transport is free. Considering the costs associated with owning or renting a car creates even more incentive to use other modes of transportation.

Also known as car sharing, carpooling is the arrangement between two or more people to travel to a shared destination in a single vehicle. Although a heavier car consumes slightly more fuel, it is usually much more efficient than two people driving separate cars towards the same destination.

Use a more fuel efficient vehicle

Driving a smaller car makes a great difference – the fuel cost is about half for a small sedan than for a very large SUV. Similarly, drive with a less powerful engine than you need. Don't pay for an eight-cylinder engine when four cylinders work just fine. Unless you're hauling heavy loads on a routine basis, the extra cost of a bigger engine results in more money spent on gasoline.

Tune the engine

A properly tuned engine maximizes power and can greatly enhance fuel efficiency. But tuning the car engine is often done to increase horsepower – that's not the way to save on fuel. Make sure the tuner gets the message.

Fixing a car that is noticeably out of tune or has failed an emissions test can improve its gas mileage by an average of 4 percent – this amount will vary depending on the nature of the repair.

Fixing a serious maintenance problem, such as a faulty oxygen sensor, can improve your mileage by as much as 40 percent.

Placing ornaments and ground effects, aerodynamics kits, and airfoils, such as deck-lid spoilers, may make you feel good, but they also increase the car's drag and make it require more fuel. Such accessories offer no real handling enhancements, although they may look nice on your car. Also, place signs or cargo on the roof so that the object angles forward. This will reduce the frontal area of the object, and it will cause less drag, and cause you to use less fuel.

Adjust tires

Make sure the tires are inflated to the right levels. Properly inflated tires can reduce fuel consumption by up to 3 percent. Your tires also lose about 1 PSI per month, and when the tires are cold (e.g., in the winter), their pressure will decrease due to the thermal contraction of the air. It is recommended to check tires at least monthly, preferably weekly. Having properly inflated tires will also help you avoid uneven wear on the tread.

Gas stations don't always have accurate equipment for this purpose. Sometimes gas stations use automatic air compressors that stop at a pre-determined level. To make sure you inflate to the right level, double-check pressure with your own gauge.

Recommended inflation pressures are for cold tires; put about 3 PSI more in if the tires have been driven on a while. Inflate to the pressure recommended by the car manufacturer, not to the level stamped on the tire.

Use the correct motor oil

Gas mileage will improve by 1 percent to 2 percent if you use the manufacturer's recommended grade of motor oil. For example, using 10W-30 motor oil in an engine designed to use 5W-30 can reduce your gas mileage by a considerable amount. Using 5W-30 in an engine designed for 5W-20 can lower your gas mileage by 1 percent to 2 percent. Also, look for motor oil that says "Energy Conserving" on the API performance symbol to be sure it contains friction-reducing additives.

Plan trips carefully

There is no more obvious way to save gas than to drive a shorter distance.

Plan your route carefully. With today's GPS route planners, it's easy to calculate a straight route with the fewest stops and diversions. It is also possible to judge which route will have the least traffic. Take highways instead of local routes or city streets when possible – the steady speed maximizes fuel efficiency.

When driving in a city, try to park in a central location, and then walk from one appointment to another, or take public transportation. Ragged stop-and-go city driving is terrible for your gas mileage. This also saves the high level of gas used in parking and pulling out in a parking lot.

Factors that determine the fuel price

Government intervention.

Governments may intervene in gasoline (referred to as petrol in some parts of the world) markets by taxation, which may raise prices for consumers within or outside the governmental territory. Similarly, certain industries may receive financial support from the government to promote commercial enterprise (a subsidy). Generally, subsidized products or services can be sold at lower prices.

Financial markets

The global oil price fluctuates constantly. The key crudes quoted are Brent and West Texas Intermediate (WTI) in the unit of US$ per barrel. The retail fuel price is closely related to the global oil price fluctuation.

Political elements such as structure, regime, personnel, and events can all affect the cost of fuel. For instance, a change in leadership from a leader who doesn't believe in climate change to one who does may result in changes to the cost of fuel for consumers based on different policies, such as choosing not to subsidize fuel. Political relationships between countries are also a factor; nations can go to war over resources, or form alliances in order to trade, both of which can affect the cost of fuel.

Geographic area

Certain geographical areas or countries in the world have an abundance of oil, while others do not have a single drop. Regional consumers within close proximity of high supplies of oil are more likely to have lower costs of fuel due to ease of access. Areas without their own supply of oil that are isolated from the rest of the world (such as islands in the Pacific) can find fuel to be relatively expensive.

Natural disaster or weather

Earthquakes, tsunamis, hurricanes, major floods, and other such nature-related phenomena can affect the production, manufacturing, and logistics of gasoline, which can possibly affect the price of fuel. For instance, a snowstorm may close certain roads, disallowing the transportation of the resource and driving up fuel costs in these areas. Hurricanes or earthquakes can damage oil refineries, abruptly halting production, which can also eventually increase fuel costs.

    Fuel Needed & Fuel Cost Calculations

In order to calculate the amount of fuel for a given trip using our fuel cost calculator or otherwise, you need to know the total distance you will be covering and the expected average fuel consumption of your vehicle. It works the same way for cars, trucks, buses, vans, SUVs, and even boats and planes. If you also want to calculate the fuel cost of a trip, then you need to know the price per gallon or price per liter at which you can by.

Our calculator supports entering distances in miles and kilometers. In terms of fuel consumption, it is very versatile as it accepts: miles per gallon, gallons per 100 miles, kilometers per liter and liters per 100 kilometers. In the US, miles per gallon and kilometers per liter would more frequently used, while in most of Europe the preferred metric would be liters to travel 100 km and gallons to cover 100 miles. The result in terms of fuel amount is in gallons or liters, and for fuel cost is in the currency you entered it in (you can simply ignore the currency sign, e.g. $ (USD)).

Make sure to account for the variation in fuel consumption when driving within city limits and on highways - usually the consumption is higher in the former case. Always fill your tank with more fuel than you anticipate you would need, especially during winter or when driving through desolate areas or when extreme weather conditions are expected.

    Formula for fuel amount

If you are using mpg (miles per gallon), then the formula for calculating the total amount of gas needed is:

Fuel = Distance / Consumption mpg

For example, if the distance is 500 miles and consumption is 20 miles per gallon, then the fuel you will need for the entire distance is 500 / 20 = 25 gallons.

If you are using gallons per 100 mi to measure consumption, then the formula for calculating the amount of fuel needed is:

Fuel = Distance / 100 x Consumption per 100 mi

For example, if the distance is 300 miles and the consumption is 5 gallons per 100 miles, you will need 300 / 100 x 5 = 15 gallons of gas.

Both formulas are applicable for metric units - km and liters, just make sure you do not mix metric units. Using an online fuel calculator will make sure you do not commit that mistake.

    How to improve fuel economy?

Don't like the numbers you see when you use our tool? If you wonder how you can improve the fuel efficiency of your vehicle so you can cover more miles (or kilometers) with less fuel, we have some tips that can result in significant savings, especially when applied consistently over time. Here is our list of 10 fuel efficiency tips :

• Drive sensibly - If you drive aggressively - too fast compared to other cars, constantly overtaking other vehicles, and rapid acceleration followed by braking, only to accelerate again wastes a lot of gas. By some estimates, quick starts and hard stops can increase fuel consumption by more than 30% ! This is why this is number one in our fuel efficiency list.
• Observe the speed limit - Different vehicles have optimal fuel economy at different velocities, but one way to increase gas mileage is to avoid driving at higher speeds. A small reduction of your average speed , say from 70 mph to 60 mph (equivalently: from 115 km/h to 100 km/h) can help you save 10 to 20% due to lower fuel consumption.
• Follow the leader - drive at about the speed of the vehicle in front of you, if they are following the first 2 tips above. This will make sure you need to accelerate and decelerate as little as possible. If possible, overtake drivers who do not follow them, as it will make it very hard for you to do so. This will result in smaller numbers from our fuel cost calculator.
• Check your tires - make sure your tire pressure is at optimal levels as indicated in the owner's manual provided by the auto manufacturer. If the pressure is too low your mileage will decrease significantly, not to mention that the car may become dangerous to drive.
• Smart routing - make sure you take optimal paths to reach your desired destination. Learn the different modes of route selection your GPS employs - the shortest is not always the fastest and idling stuck in traffic will waste fuel. Use services such as Google Maps to check for traffic congestions on the planned route. Using a route you know well can also help improve fuel efficiency, since you will know in advance where it makes sense to increase speed and where it does not, because of a traffic light just ahead.
• Air conditioning - turning it off will most likely improve your fuel efficiency by 10-15%, and will result in you having more power to accelerate quicker when needed. If it is necessary, make sure you do not set it to unreasonably low or high levels. Air temperature in the range between 64°F - 75°F (18°C - 24°C) is comfortable for most people. Due to the law of thermodynamics, each subsequent degree of heating or cooling requires progressively more energy to accomplish and maintain.
• Remove excess weight - make sure you remove any unneeded heavy items you have in your trunk. One of the untold benefits of losing weight is that your car will be a bit more efficient as well.
• Turn cruise control ON - when on a highway, make sure to use your cruise control option. By keeping your speed constant, it will most likely save gas and result in lower fuel costs.
• Avoid idling - idling means 0 miles per gallon and the larger the car engine, the more gas is wasted when idling. Avoid excessive idling, when possible, in line with point #5 above to keep fuel costs low.
• Maintain your vehicle - a well-maintained car, truck, van, SUV, etc. will operate at greater efficiency. Exact fuel savings are hard to calculate, as it will depend on the type of maintenance work your vehicle needs. However, good maintenance is sure to lead to fuel savings and smaller cost numbers coming out of our calculator.

All the above advice is fine, but what do you do if you have been following the above advice, yet our tool still shows you numbers that are so high you want to cry? Well, it is most likely time for a new car, or it could be just the fuel price fluctuations over which, unfortunately, neither you nor we have much influence, individually. Fuel prices in most places contain license fees and other state or local government taxes, in some places reaching as much as 50% of the final price. Financial market fluctuations, natural disasters or extreme weather, crisis, as well the geographical area you are in and the local fuel suppliers all influence the price of gas. All you can do is try to observe them and predict when you can get a more decent price.

Why you should know how much fuel you will need and the cost before buying gas for your trip

With the price of gas going up daily and your buying power steadily declining due to inflation, the unfortunate truth is that it is unwise to plan a road trip without first calculating the cost of gas. After all, gas is not the only thing you will need.

Before you plan your trip, you need to recognize that there can be lots of unexpected expenses when you are away from home. As such careful planning and a detailed budget are most important for a worry-free trip. You can typically expect to spend money on:

• Entertainment;
• Emergency repairs;
• Emergency medical care.

🙋 While we took care of the fuel price in this calculator, you may also check out our speed calculator to help you plan your activities. If you plan to lease a car for your trip, our car lease calculator may also interest you.

Process used by our fuel cost calculator to find how much gas you will need as well as the cost of your trip

To calculate how much fuel you will need, here is the formula used by our fuel cost calculator:

Fuel amount= Distance / Fuel efficiency

For instance, if you wish to travel 100 km with a vehicle with a fuel efficiency of 5 kilometers per liter , substitute these variables into the formula above:

Fuel amount= 100 / 5 = 20 liters

Our calculator also uses the amount of fuel and the cost of gas in your area to calculate the total cost of your trip. For this, we use the following formula:

Trip cost = Fuel amount × Fuel price

So using the amount of fuel given in the above problem, if the price of gas was $7 , then to calculate the amount of money needed for the trip, we put these values into the formula, and we get:

Trip cost = 20 × 7 = $140

What is the best way to take a road trip on a small budget?

If you are planning a road trip for your vacation, but your budget is relatively small, here are a few things you can do:

• Go during the offseason. Vacation rentals cost less in the offseason. This price reduction is because the demand for these places is relatively low during the off-season. So owners and agents reduce the price to attract more visitors.
• Take a road trip with others willing to share the cost. Sharing the cost will reduce your individual payment. For instance, if the fuel price for the trip is $1000, you will pay less by splitting that cost five ways between friends. You can do this using our gas cost calculator .
• Try camping to reduce the cost of accommodation. Campsites cost less than the average hotel.
• Research fun, entertaining activities that you and your friends can do free of cost or for a small fee. For example, use a map to explore with your team rather than hiring a tour guide.
• Pack food that you can quickly fix on the go rather than eating in restaurants. The cost of food can eat into your vacation money. As such, finding ways to eat for less can make the difference in the amount and type of activities you will be able to engage in.

Is it cheaper to drive or fly for long distances?

Due to the additional costs for items such as food and accommodation for several days, a road trip across great distances can cost significantly higher for long-distance trips than flying. This can, of course, be affected by these factors:

• Number of persons on the trip;
• Whether the cost is shared or not; and
• Type of accommodation used.

How do I calculate fuel cost?

To calculate the fuel cost, we use one of the following formulas:

• Fuel cost = (Distance / Efficiency per gallon) × Cost per gallon
• Fuel cost = (Distance / [100 × Consumption per 100 mi]) × Cost per gallon

Use the first formula if you have the car's efficiency in miles per gallon (mpg).

On the other hand, we use the second formula if the consumption is in gallons per 100 miles.

How do I calculate fuel cost per month?

To find the fuel cost per month:

• Multiply the distance per day by the number of days per month.
• Divide this by your vehicle’s efficiency per gallon.
• Multiply the answer by the price per gallon.

How much does a gallon of gas weigh?

A gallon of gasoline weighs approximately 6.073 lbs in the US.

Gasoline contains additives that affect its final weight. These vary from country to country. As such, it is impossible to give an exact weight worldwide.

Fuel Cost Calculator

Fuel Cost Calculator is a tool to estimate gas costs for your trip. The gas cost calculator is calculated based on the distance in miles or km, miles per gallon, and the gas price per gallon.

Gas Mileage Calculator

The gas mileage calculator is useful for anyone who wants to calculate the costs of driving from one city to another. If you are planning a route trip and is price conscious, then gas costs is definitely something you may want to take into account. The distance, the mileage, and the total fuel costs can add burden to your budget especially if you are travelling long distance. With the rise in gas prices, the cost on fuel can get out of control quickly if you don't plan carefully. At fuel cost calculator, you can use our free gas estimator to help you estimate the total costs on gas and plan accordingly.

How the fuel cost calculator works?

The fuel cost calculator uses the trip distance, miles per gallon, and the current gas price to calculate the total cost when you travel from one location to another. 1. Trip Distance - the distance in miles or kilometers between the two locations. 2. Miles Per Gallon - the number of miles or kilometers that you can travel with 1 gallon of gas. You will travel fewer mileages per gallon when travelling locally, and many more mileages when you are on a highway. The miles per gallon is the average miles that you can travel with one gallon of gas. 3. Gas Price - the current gas price per gallon. With only these 3 inputs, the gas cost calculator will calculate the total costs for you.

How to save money on fuel cost?

There are many ways to save on fuel cost when you are travelling locally and sometimes in long distance. 1. Public Transportation - can sometimes save you money than driving. With driving, you may have to pay toll and stuck in traffic during rush hours. You may also need to pay for parking fees at your destination. With public transportation such as subway, you can often get away with traffic and can do activies that you like during commute such as reading or playing with your phone. If you are someone who does not enjoy driving, taking public transportation may not be a bad option. 2. Carpool - if public transportation is not an option. You can carpool with a coworker if you are driving to work. Carpool allows both of you to save money and having someone to keep you company while driving so you don't get bored. 3. Electric Car - you can also get an electric vehicle like a Tesla to save money on gas costs. With a gas car, you may spend more money on gas than the electricity cost of an electric car. It may be most costly upfront to buy an electric car, but it may save you money in the long run if you are using your car on a daily basis or travelling a lot.

Fuel Cost Table

The fuel cost table shows you the total costs based on your trip distance, price per gallon, and MPG.

Fuel Cost Calculator – How Much will the Trip Cost?

On this page is a fuel cost calculator , which lets you estimate the cost of fuel you'll spend on a trip. Enter the trip distance, your cost of fuel, and your vehicle's fuel efficiency and the tool will guess how much you'll spend to power your trip.

Fuel Cost Calculator

Using the fuel cost calculator.

The fuel cost calculator is relatively straightforward, but you will have to make a few choices for us to guess at what you'll spend. Please fill in the following fields:

• Trip Distance (km or mi) - Enter the distance you'll be traveling on the trip, including any excursions you'll take off the main path. You don't need to enter units – the tool will assume miles or kilometers based on what you choose for fuel efficiency.
• Gas Cost (gal or l) - Enter how much you estimate gas to average over your trip. Use the pulldown menu to select your currency. There's no need to enter gallons or liters; the tool will use your choice under fuel efficiency.
• Fuel Efficiency - Enter the efficiency of your vehicle, followed by whether it's measured in "kilometers per liters" or "miles per gallon". Note that for the former, the output will be based on kilometers and liters, while for the latter choice it'll be based on miles and gallons.

Fuel Cost Calculator Outputs

Once you're happy with the above inputs, hit the "Compute Fuel Cost" button. The tool will give you two outputs that you can factor into your trip planning:

• Fuel Used - Based on your inputs, our estimate of how much fuel you'll use over your trip.
• Cost - Again, based on your inputs, a guess at how much you'll be spending on fuel costs for your trip.

Have a Great Trip!

Hopefully, this was a useful tool to help you budget your fuel costs on your next trip. We wish you safe travels – come back soon, or visit one of our other car, truck, van, and vehicle calculators:

How Is the Distance Between Cities and Points Calculated?

Distance and travel time calculation algorithm.

This route calculation tool harnesses the power of shortest path search algorithms within a weighted road graph, employing sophisticated algorithms like Dijkstra, A-Star, and Contraction Hierarchies . Unlike conventional calculators that use distance or travel time as the graph weight, our system optimizes drive time for vehicles, favoring routes on higher-class roads for a smoother journey.

The backbone of this tool is built on OpenStreetMap data, ensuring our road graphs are accurate and up-to-date. We calculate distances between road segments with the haversine formula , using precise GPS coordinates to measure the Great Circle Distance. This formula is pivotal for calculating "air distance" or "straight line distance" between two points, taking into account the curvature of the Earth.

Road distances, however, diverge from straight line distances due to the natural curvature and layout of roads . To address this, roads are represented as segmented lines, and the haversine formula is applied to each segment, allowing for precise calculation of the journey length between any two points.

Recognizing that cities encompass large areas, our tool selects a central point within each city for distance calculations between cities. For personalized route planning, users can specify exact addresses or select points on the map. Additionally, the route's start and end points can be adjusted directly on the map for enhanced customization.

Travel time calculations break down the route into segments, evaluating the maximum permitted speed for each segment to estimate the fastest possible travel time.

It’s important to note that while our route calculation relies on advanced computer modeling for accuracy, no model is perfect . We encourage users to plan with a margin for adjustment to ensure a reliable and efficient journey.

Other Methods of Calculating Distances

One simple way to measure distance is by using a highway atlas. By tracing a route with your eye and rolling a curvimeter along it, you can gauge the distance. Estimating travel time involves assuming an average speed of 50 miles/hour on major intercity roads. Although this method provides rough estimates, it's straightforward.

In the absence of a curvimeter, a ruler can serve as a substitute. Start by aligning the ruler's zero mark with your route's beginning and follow the road's bends closely. Then, translate the measured length into kilometers or miles using the map's scale, which is typically provided in the atlas.

For those seeking a more streamlined approach, pre-calculated distance tables specifically for the USA are available on websites, atlases, and guidebooks. Particularly useful for journeys between major cities, these tables streamline planning, although they may omit smaller locales.

Your last-minute guide to Monday's total solar eclipse

A total solar eclipse will cross North America on Monday , offering millions a rare opportunity to see afternoon skies temporarily darken as the moon blocks the face of the sun.

Tune into NBC News NOW as Lester Holt hosts a two-hour special at 2 p.m. ET Monday from Indianapolis Motor Speedway.

The eclipse's path fortuitously cuts across Mexico, 15 U.S. states and a small part of eastern Canada. In all other states in the continental U.S., viewers will be treated to a partial solar eclipse, with the moon appearing to take a bite out of the sun and obscuring part of its light.

Here’s everything you need to know about the rare celestial event.

What is a solar eclipse?

Solar eclipses occur when the sun, moon and Earth align. The moon passes between Earth and sun, temporarily blocking the sun’s light and casting a shadow on Earth.

A total solar eclipse is when the moon fully obscures the sun, whereas a partial solar eclipse means it blocks just a portion of the sun’s face.

Solar eclipses occur only with the new moon. Because the moon’s orbit around Earth is tilted, the three bodies don’t always line up in a way that creates an eclipse.

“Imagine if the moon’s orbit were in the plane of Earth’s orbit around the sun — if that were the case, then every new moon, you’d have a total solar eclipse and every full moon, you’d have a lunar eclipse,” Neil DeGrasse Tyson, director of the Hayden Planetarium at the American Museum of Natural History, told NBC News. “So, because things don’t always align, it lends to the rarity of the event and the specialness of the event.”

Where and when will the eclipse be visible?

This year’s eclipse will follow a slightly wider path over more populated areas of the continental U.S. than other total solar eclipses have in the recent past.

NASA estimates that 31.6 million people live within what’s known as the path of totality, where the total solar eclipse will be visible. An additional 150 million people live within 200 miles of the path, according to the agency.

The path travels through Texas, Oklahoma, Arkansas, Missouri, Illinois, Kentucky, Indiana, Ohio, Pennsylvania, New York, Vermont, New Hampshire and Maine. Tiny parts of Michigan and Tennessee will also be able to witness totality if conditions are clear.

After the eclipse crosses into Canada, it will pass over southern Ontario, Quebec, New Brunswick, Prince Edward Island and Cape Breton, at the eastern end of Nova Scotia.

Those outside the path of totality can still take part in the astronomical event by viewing a partial solar eclipse — visible throughout all 48 states of the contiguous U.S. — or a NASA livestream.

The timing, including how long totality lasts, depends on the location, but some spots will see the moon fully cover the sun for up to 4 minutes and 28 seconds.

Below is a list of timings for some cities along the path of totality, as  provided by NASA . A number of other resources, including NationalEclipse.com  and  TimeandDate.com , can also help people plan.

• Dallas: Partial eclipse begins at 12:23 p.m. CT and totality at 1:40 p.m.
• Little Rock, Arkansas: Partial eclipse begins at 12:33 p.m. CT and totality at 1:51 p.m.
• Cleveland: Partial eclipse begins at 1:59 p.m. ET and totality at 3:13 p.m.
• Buffalo, New York: Partial eclipse begins at 2:04 p.m. ET and totality at 3:18 p.m.
• Lancaster, New Hampshire: Partial eclipse begins at 2:16 p.m. ET and totality at 3:27 p.m.

How to safely view a solar eclipse

It is never safe to gaze directly at the sun, even when it is partly or mostly covered by the moon. Special eclipse glasses or  pinhole projectors  are required to safely view solar eclipses and prevent eye damage. Failing to take the proper precautions can result in severe eye injury,  according to NASA .

Eclipse glasses are thousands of times darker than normal sunglasses and specially made to enable wearers to look at the sun during these kinds of celestial events.

Sky-watchers should also never view any part of the sun through binoculars, telescopes or camera lenses unless they have specific solar filters attached. Eclipse glasses should not be used with these devices, as they will not provide adequate protection.

However, during the few minutes of totality, when the moon is fully blocking the sun, it is safe to look with the naked eye.

Beware of fake eclipse glasses. On legitimate pairs, the lenses should have a silver appearance on the front and be black on the inside. The manufacturer’s name and address should be clearly labeled, and they should not be torn or punctured. Check, as well, for the ISO logo and the code “IS 12312-2” printed on the inside.

If you don’t have eclipse glasses, you can make a homemade pinhole projector, which lets sunlight in through a small hole, focuses it and projects it onto a piece of paper, wall or other surface to create an image of the sun that is safe to look at. 

All you need is two pieces of white cardboard or plain white paper, aluminum foil and a pin or thumbtack. Cut a 1- to 2-inch square or rectangle out of the center of a piece of white paper or cardboard. Tape aluminum foil over that cut-out shape, then use a pin or thumbtack to poke a tiny hole in the foil.

During the eclipse, place a second piece of white paper or cardboard on the ground as a screen and hold the projector with the foil facing up and your back to the sun. Adjusting how far you hold the projector from the second piece of paper will alter the size of the image on the makeshift screen.

What to look for while viewing the total solar eclipse

For people along the path of totality, there are some fun milestones to keep track of as the total solar eclipse unfolds.

As the eclipse progresses and the sun gets thinner in the sky, it will start to get eerily dark, according to Tyson.

When the last beams of sunlight are about to become obscured, look out for the “diamond ring effect”: The sun’s atmosphere will appear as an illuminated halo, and the last light still visible will look like the diamond of a giant ring.

As the sunlight decreases even further, an effect known as Baily’s beads will be created by the moon’s rugged terrain. Tiny “beads” of light will be visible for only a few seconds around the dark moon, as the last bits of sunlight peer through the moon’s mountains and valleys.

When the moon is fully blocking the sun, it is safe to remove eclipse glasses and look at the total solar eclipse with the naked eye.

Some lucky sky-watchers may even catch a glimpse of a comet .

Comet 12P/Pons-Brooks — nicknamed the “ devil comet ” because an eruption last year left it with two distinct trails of gas and ice in the shape of devil horns — is currently visible from the Northern Hemisphere as it swings through the inner solar system.

The comet can be seen in the early evenings by gazing toward the west-northwest horizon. During the eclipse, when skies darken during totality, it may be possible to see the comet near Jupiter, but its visibility will depend on whether it’s in the middle of an outburst and thus brighter than normal.

Most likely, all eyes will be on the alignment of the moon and sun.

“Most people won’t even notice,” Tyson said. “But if you know to look, it’s there.”

When is the next solar eclipse?

The next total solar eclipse will be in 2026, but it will mostly pass over the Arctic Ocean, with some visibility in Greenland, Iceland, Portugal and northern Spain. In 2027, a total solar eclipse will be visible in Spain and a swath of northern Africa.

The next total solar eclipse visible from North America will be in 2033, but only over Alaska. Then in 2044, a total solar eclipse will cross Montana, North Dakota, South Dakota, parts of Canada and Greenland.

The next total solar eclipse to cross the continental U.S. coast-to-coast in will occur in 2045. The path of totality for that eclipse will cut through California, Nevada, Utah, Colorado, New Mexico, Oklahoma, Kansas, Texas, Arkansas, Missouri, Mississippi, Louisiana, Alabama, Georgia and Florida.
