Question 1

How does weight change on other planets?

Accepted Answer

Weight is the force of gravity pulling on your mass. Since each planet has a different mass and radius, the surface gravity differs. For example, Jupiter's gravity is 2.34× Earth's, so you would weigh 2.34 times more there. Your mass stays the same everywhere.

Question 2

Why would I weigh less on the Moon?

Accepted Answer

The Moon's surface gravity is only about 0.165 times Earth's because the Moon is much smaller and less massive. So a 100 kg person on Earth would weigh about 16.5 kg on the Moon.

Question 3

What's the difference between mass and weight?

Accepted Answer

Mass is the amount of matter in your body — it never changes. Weight is the gravitational force on that mass (W = m × g). This calculator shows how your weight (the force) changes by planet, while your mass remains constant.

Question 4

Would I actually be able to stand on Jupiter or the Sun?

Accepted Answer

No — Jupiter and Saturn are gas giants with no solid surface, and the Sun is a plasma star. The values shown are theoretical surface-gravity calculations, useful for physics learning and curiosity.
