Your Weight on Other Planets
How much would you weigh on Mars, Jupiter, or the Moon? Enter your weight to see it on every planet in the solar system.
How it works
Why would I weigh less on Mars?
Weight is the pull of gravity on your mass. Your mass (how much "stuff" you're made of) stays the same everywhere, but a planet's gravity depends on its mass and size. Mars has about 38% of Earth's surface gravity, so a 150 lb person would weigh about 57 lb there.
How is it calculated?
Weight on a planet = your Earth weight × (that planet's surface gravity ÷ Earth's surface gravity of 9.81 m/s²). Gravity values come from NASA's planetary fact sheets.
Can you really stand on Jupiter?
No. Jupiter, Saturn, Uranus, and Neptune are gas and ice giants with no solid surface. Their "surface gravity" is measured at the cloud-top level where the atmospheric pressure equals Earth's at sea level.
How does the jump height work?
With weaker gravity, the same leg push sends you higher: jump height scales with 1 ÷ gravity. On the Moon, an 18-inch jump becomes about 9 feet. (This ignores spacesuits!)
