Frequently asked questions
Multiply your Earth weight by the planet's surface gravity ratio. On Mars (0.377 of Earth's), a 70 kg person weighs about 26.4 kg.
Mass stays the same everywhere; weight is the force of gravity on that mass, which varies with each body's surface gravity.
Of the major planets, Jupiter has the strongest surface gravity, about 2.36 times Earth's, so you would weigh the most there.
The Moon's surface gravity is only about one sixth of Earth's, so you weigh roughly 16% of your Earth weight there.
