How much would you weigh across the solar system?
Enter your weight on Earth and watch it change on every world. Your mass never moves, but gravity on the Moon, Mars, Jupiter and the Sun rewrites the number on the scale.
You on Earth
Surface gravity is measured relative to Earth, where Earth equals 1. Multiply your Earth weight by that ratio to get your weight on any body.

Weight, mass and gravity, explained
How Gravity Varies Across the Solar System
Surface gravity depends on a celestial body's mass and radius. Jupiter, the most massive planet, has 2.36 times Earth's surface gravity despite being a gas giant. Mars has only 0.377g due to its smaller mass. The Moon's gravity is just 0.166g, which is why Apollo astronauts could bounce across the lunar surface. These differences profoundly affect how much you would weigh on each world.
Weight vs Mass in Space
Your mass (the amount of matter in your body) stays constant everywhere in the universe. Weight, however, is the force of gravity pulling on your mass. On Jupiter, a 150-pound person would feel 354 pounds of gravitational force. On Pluto, that same person would weigh only about 10.7 pounds. Astronauts in orbit experience weightlessness not because gravity is absent, but because they are in continuous free fall.
Common questions
Why is Pluto included if it is not a planet?
Pluto was reclassified as a dwarf planet in 2006, but it remains a fascinating celestial body with known surface gravity (0.071g). It is included here because of its cultural significance and because people are curious about how extreme low gravity would feel. On Pluto, a 150-pound person would weigh only about 10.7 pounds.
Could humans survive the gravity on Jupiter?
Jupiter's surface gravity is 2.36 times Earth's, meaning a 150-lb person would feel like they weigh 354 lbs. While uncomfortable, this level of gravity alone would not be fatal. However, Jupiter has no solid surface, and its atmosphere of hydrogen and helium with extreme pressures and temperatures makes it uninhabitable.
Why do astronauts float in the space station?
Astronauts appear weightless because the International Space Station is in constant free fall around Earth, not because gravity is absent. At the ISS altitude of about 250 miles, gravity is still about 90% of what it is on Earth's surface. The station and everything inside it fall toward Earth at the same rate, creating the sensation of zero gravity.
How is surface gravity calculated?
Surface gravity is calculated as g = GM/r2, where G is the gravitational constant, M is the body's mass, and r is its radius. For simplicity, surface gravity is often expressed as a ratio relative to Earth (where Earth = 1.0). These ratios are what this calculator uses to determine your weight on other worlds.
Surface gravity ratios are approximate values for each body. Gas giants and the Sun have no solid surface to stand on, so those figures show the gravitational pull at the visible cloud tops or photosphere. For fun and learning only.
