How Much Would You Weigh on the Moon?

If you weigh 60 kg on Earth, you'd weigh 10 kg on the Moon. That's why Apollo astronauts bounced around like they were on a trampoline. The math is simple: weight = mass × gravity. The Moon's surface gravity is 1.62 m/s², about 16.5% of Earth's 9.8 m/s².

But wait — you're not actually losing mass

Your mass — the amount of stuff you're made of — doesn't change. You're still 60 kg of person. What changes is the force of gravity pulling on that mass. On Earth, that force presses you down at 9.8 m/s². On the Moon, it presses you at 1.62 m/s². Your bathroom scale is measuring that force, not your mass.

What about other planets?

On Mars, you'd weigh about 23 kg (if you're 60 kg on Earth). On Venus, 54 kg — almost Earth. On Jupiter — which has no solid surface — about 152 kg at the cloud tops. On a neutron star? About 60 billion kg. You would not be standing. You'd be a thin film of atoms.

Why does gravity change so much?

Gravity depends on two things: mass and distance. More mass = more gravity. Smaller radius = you're closer to the center = more gravity. The Moon is less massive than Earth, so less gravity. Jupiter is way more massive, so more gravity. A neutron star has the mass of the Sun squeezed into a 20 km ball, so the gravity at its surface is insane.
