Find out how much you would weigh on other planets.

You may have wondered how much you would weigh on other planets in the solar system if you were a science fiction fan, space enthusiast or one of the millions who have watched astronauts gamboling about the moon's surface.

To sort this out, you need to know a little about physics.Humans would grow taller on Mars than Earthlings.

The force of gravity exerts on an object.Mass is the measure of an object's inertia, its resistance to being moved or stopped.Your mass is the same across the universe, but your weight changes depending on the forces acting on you, which varies from planet to planet.

The Law of Universal Gravitation states that everything that has mass attracts every other thing with mass, pulling with a force proportional to the product of the two objects' mass and the distance between their centers.

Although gravity increases linearly as objects grow larger, it decreases as the distance between them increases.The space between you and the planet's center of mass is referred to as the surface gravity distance.This means that a planet's size has a bigger impact on its gravity than it does on mass.

We can see that this leads to a surprising result if we don't get bogged down in the math.Jupiter is the most massive planet in the solar system and tips the scales at over 300 times the mass of the Earth.You might think you would weigh more there than here.If you could find a way to stand on gas clouds, Jupiter's gravity would drop off by a factor of 12 at its surface.

That doesn't mean that Jupiter's gravity to Earth is more than 112.If you want to calculate the ratio between Earth's surface gravity and that of any other body, you have to use the formula above.We will spare you the work.

Your weight on the surface of each planet will be determined by the number of mass and surface gravity.If you weigh 150 pounds.You would weigh 351 lbs. on Earth.A total of 159 kilograms.On Jupiter, 57 lbs.A total of 26 metric tons.There is a mere 9 lbs. on Mars.A total of four kilomes.There is a dwarf planet.

Even though Mars is twice as big as Mercury, they have the same proportional gravity.Mars is larger than Mercury because of the inverse-square relationship between gravity and distance.

The difference in surface gravity is counterbalanced by the fact that Uranus is 4.2 times larger than Venus.
