How much would you weigh on other planets?
Your mass never changes — but your weight is just gravity’s pull on that mass, and every world pulls differently. Type your weight below and watch it swing from featherweight on the Moon to crushing on Jupiter, all computed from NASA surface-gravity data.
Tiny and dense — you’d weigh about a third of your Earth weight.
Almost Earth’s twin in size, so your weight barely changes.
Home base — the weight you already know, and our 1.0× reference point.
Just 1/6 of Earth’s pull — this is why the Apollo astronauts bounced.
Roughly a third of Earth — you could jump nearly three times higher.
The heavyweight champion: ~2.5× your weight at its cloud tops (it has no solid ground).
Despite being 95× Earth’s mass, it’s so puffy your weight is almost unchanged.
Bigger than Earth, yet you’d weigh slightly less — size isn’t everything.
One of only two worlds here where you’d weigh MORE than on Earth.
Why your weight changes but you don’t
Step on a scale and it reads your weight — the force with which Earth’s gravity pulls you down. Fly to Mars and the scale reads about a third of that, because Mars pulls far more gently. But you haven’t shrunk: your mass, the actual amount of matter in your body, is identical on Mars, the Moon, or Jupiter. Weight is mass × gravity, so only the gravity part travels.
That’s why you’d weigh most on Jupiter (~2.5× Earth) and least on the Moon (~1/6). It’s also behind two great space-trivia curveballs: Saturn is 95 times Earth’s mass yet its gravity is almost identical to ours, because it’s so enormous and low-density that its cloud tops sit far from its centre — and Uranus, though bigger than Earth, would leave you slightly lighter. Bigger planet doesn’t always mean heavier you.
