Weight on Other Planets Calculator
See what you'd weigh on every planet, the Moon, and Pluto, based on each world's surface gravity.
Your mass never changes — but weight is mass times gravity, and every world pulls with a different strength. On the Moon you'd weigh about a sixth of your Earth weight; on Jupiter, more than twice as much.
| Mercury | 56.7 lb |
| Venus | 136.1 lb |
| Moon | 24.9 lb |
| Mars | 56.6 lb |
| Jupiter | 354 lb |
| Saturn | 159.8 lb |
| Uranus | 132.9 lb |
| Neptune | 171 lb |
| Pluto | 9.5 lb |
How it works
Your weight is really a measurement of how hard gravity pulls on you. Since every planet and moon has a different gravitational pull, your weight changes from world to world even though your body — your mass — stays exactly the same.
The tool multiplies your Earth weight by each body's surface gravity relative to Earth. The Moon sits at about 0.166, so you'd weigh roughly a sixth as much there; Jupiter's is about 2.36, so you'd feel more than twice as heavy.
Type your weight in pounds or kilograms and the table fills in instantly. It's a fun way to picture just how differently gravity behaves around the solar system.
Frequently asked questions
Why do I weigh less on the Moon?
The Moon has far less mass than Earth, so its surface gravity is only about a sixth of ours. Same you, much gentler pull, so the scale reads about one-sixth of your Earth weight.
Where would I weigh the most?
Of the places listed, Jupiter — its surface gravity is roughly 2.36 times Earth's, so a 150 lb person would tip the scales near 354 lb there. Pluto is the featherweight at about 6% of your Earth weight.
Does my mass change too?
No. Mass is the amount of matter in you and it's the same everywhere. Only weight — mass times local gravity — changes from planet to planet.
