# How Much Do I Weigh on Other Planets?

The answer to the question ‘how much do I weigh on other planets’ will vary depending on the mass of the object the density of the planet’s atmosphere and the distance from its centre. If you’ve ever jumped high in the air while on the Moon you know that the Moon’s gravity is surprisingly strong but how heavy is it on other planets? The following guide will show you how to determine the answer.

Activity III focuses on weight. Students can calculate their weight on other planets using the Solar System Data Table or use books from the school library. They can then create a comparison chart of weight and determine the property of each planet that affects its weight. Once they have a general idea of how much each planet weighs students can begin the process of determining what properties make it different than earth.

The web site Bill Arnett’s Nine Planets contains a calculator for how much you would weigh on different planets. You can even enter your Earth weight to see how much you’d weigh on another world. You’ll be surprised at how much you’d weigh on another world! There’s no need to guess – use this calculator to find out how much you’d weigh on the planet of your dreams!

The weight on planets varies according to the size and mass of the body as well as its distance from the center of the planet. If you’re a star-bomb-like astronaut this calculator can be a helpful resource. With a simple input of your current weight the calculator can calculate how much you’d weigh on different planets. Then a few clicks of the mouse will show you how much you’d weigh in a planet similar to your own.

## Mass

If you’ve ever wondered how much you would weigh on other planets it might surprise you to know that there are several variables involved including gravity and mass. The distance to the planet’s center the mass of the surface and the surface’s size all play a part in how much you weigh. But one thing’s for sure: it’s not impossible to jump high on the Moon.

Astronomers have discovered large planets around massive stars far outside our solar system. This information can help them calculate how much these planets weigh. To help you make an accurate estimate of the weight of a newly discovered planet CERES has created a calculator that helps astronomers calculate its mass. You can use this calculator to get a general idea of how much you’d weigh on any extra-solar planet.

Whether you’ll be carrying a bag of groceries or a backpack for your gear you’ll need to calculate your weight on the other planet. The weight on other planets will vary from yours on Earth largely because of the mass and distance to the planet’s center. The weight of your bag on an alien planet will be far different from your own. So be sure to calculate the weight and volume of your backpack based on the weight of your clothing and the mass of the planet you’re travelling to.

The final planet in the Solar System Neptune is a gas giant so it’s not surprising that it has a significantly higher density and gravity than Earth. A person who weighs 68 kg on Earth would weigh 76.5 kg on Neptune. On the Moon however there is no comparison between the size of the moon and Neptune. In fact the Moon is only 1.6 times the mass of Earth meaning that an average size would translate into about eleven kilograms on Mars.

## Distance from center

There are several ways to determine how much you would weigh on other planets and each one will be different from the other. Your weight on Earth would be much heavier than you would weigh on other planets and vice versa. The weight of an object on an alien world depends on several factors including its mass its distance from the planet’s center and its size. This calculator can give you an accurate estimate of how much you would weigh on another planet.

The moon is one of the planets that isn’t directly comparable to Earth. This means that it has seventeen percent of Earth’s gravity. You can find out your weight on the moon by multiplying your total weight by 0.165. If you’re interested in finding out how much you would weigh on other worlds Bill Arnett’s web site is a great place to start. The Nine Planets web site has many interesting facts and useful calculators.

The weight you would need to carry on other planets would depend on its mass and gravity. If you’re weighing 81 kg on Earth you’d need to multiply that number by 1.19 on Pluto. The calculation can be done for any planet. However the exact weight of an astronaut on Pluto would be different than the weight on Neptune. So when you’re planning your trip to the moon you should know how much you weigh on Earth.

The activity III on weight is a great way to get kids to understand how much people weigh on other planets. Using the Solar System Data Table or books from the school library students can find the weight of other planets. Make comparison charts and determine which property of the planet affects its weight. For example the surface area of a planet with a large radius will be more dense than one that is near a Sun.

## Density

The answer to the question ‘How much do I weigh on other planets?’ is different than the answer to the question ‘How much do you weigh on Earth?’ The answer depends on a number of factors including the mass of the celestial body and the distance from its center. The following chart gives you a rough estimate of your weight on other planets. You can also find the weight of other planets at Bill Arnett’s Nine Planets web site.

The mass of a person remains the same on all planets but the weight of a person on another world changes. This is because the planets differ in size mass and diameter. If you know your own weight you can use the surface gravity of a planet to estimate your weight on another world. The conversion factor for kilograms and pounds is the same. The weight of a person on a planet differs from that on Earth but the mass of an astronaut is constant.

Weight on another planet is calculated by multiplying your weight on Earth by the planet’s surface gravity. For example if you weigh 158 pounds on Earth you’d be weighing 154 lbs on Neptune which has a gravity of 1.19 times that of Earth. The same process can be used to determine your weight on Pluto. The variables involved in the calculation are F G m 1 and m 2 (the mass of your body and that of the planet) and r the distance between the centers of the two bodies.

The size and mass of other planets differ based on their composition and mass. Venus and Mars are similar to the Earth in size and mass so a person weighing 68 kg on Earth would weigh 61.6 kilograms on Venus. Mars is smaller having only 11% of the mass of Earth. Mars is larger and less dense than Mercury but still much smaller than Earth. As a result Pluto was demoted to dwarf planet status and became the second largest planet.

## Gravitational force

Unlike the Earth planets other than Earth exert a gravitational pull. This force varies depending on mass and density with the denser planets exerting more force. On Earth falling objects experience an acceleration of 9.8 m/s2 or 1 g. However this acceleration is much less than what you would experience if you fell from a planet with a density of one million times Earth’s. Because of this gravitational force is measured in percentages of Earth’s g-force.

The larger your mass the greater the gravitational pull. Therefore when you weigh 200 pounds you will experience a higher weight on the scale. Smaller celestial bodies such as the moon Venus and Mars have much weaker gravitational pulls than our planet. And of course the Moon with only 1/6 the mass of Earth has less gravity. But what if you’re visiting another planet and want to know how much you’d weigh on the other planets?

Earth’s gravity exerts a greater pull on us than that on other planets. So if you were to visit Mercury you’d probably weigh only 38 pounds if it was 318 times heavier than Earth. Jupiter on the other hand would be 318 times heavier than Earth. If you’re wondering what you’d weigh on other planets consider your weight and mass in relation to your size.

Despite the similarities in weight and mass there are several differences in the way they are measured. For example planets with no atmosphere or thin atmosphere have very little gravity. Similarly planets with cold temperatures have very little gravity. However planets with a large diameter will have the greatest gravitational pull. In other words if you weigh 81 kg on Earth you would weigh 151 kg on Pluto.
