Calculate your weight on every planet, moon, and dwarf planet in the solar system. Includes gravity comparison chart, jump height estimates, and planetary data.
Your weight depends on the gravitational pull of the body you are standing on. While your mass stays the same everywhere, your weight — the force of gravity on your mass — changes dramatically across the solar system. On the Moon you would weigh only 16.5% of your Earth weight, while on Jupiter you would feel 2.5 times heavier.
Surface gravity depends on both a body's mass and its radius. Jupiter is 318 times more massive than Earth but its much larger radius means surface gravity is "only" 2.53 times Earth's. Conversely, a dense but small body like Io has surface gravity similar to the Moon despite being larger.
This calculator computes your weight on 15 bodies including all eight planets, the Moon, Pluto, and major moons like Europa, Titan, and Ganymede. It also estimates how high you could jump on each body based on your Earth jump height, provides a visual gravity comparison chart, and displays detailed planetary data for reference.
This calculator is useful whenever you want a quick, concrete comparison of how gravity changes your weight on different worlds. It also helps explain why low-gravity bodies make jumping easier and why massive planets like Jupiter feel so different from Earth even when they are made of the same kinds of materials.
Weight = mass × surface gravity (W = mg). Jump height on another body = Earth jump height × (g_Earth / g_body), assuming the same takeoff energy. Surface gravity: g = GM/R², where G is the gravitational constant, M is the body's mass, and R is its radius.
Result: 26.6 kgf on Mars, 1.31 m jump height
A 70 kg person weighs about 26.6 kgf on Mars (vs 70 kgf on Earth) because Mars surface gravity is 3.72 m/s², only 38% of Earth. They could jump 1.31 m high instead of 0.5 m.
Weight is a force, so it changes with surface gravity even when mass stays the same. That is why the same person can feel light on the Moon and much heavier on Jupiter.
A body with more mass does not always produce stronger surface gravity. Radius matters too, because gravity falls with the square of distance from the center. Large, low-density worlds can have gravity that is less dramatic than their size suggests.
The jump-height estimate assumes the same takeoff effort. It is a simple way to visualize how lower gravity affects movement, but it does not account for atmosphere, terrain, or suit mass.

Mass is the amount of matter in an object (measured in kg) and is constant everywhere. Weight is the gravitational force on that mass (measured in Newtons or kgf) and changes depending on surface gravity.
Jupiter, with surface gravity of 24.79 m/s² (2.53 times Earth). Among rocky planets, Earth has the strongest gravity.
About 16.5% of your Earth weight. A 70 kg person would weigh about 11.6 kgf on the Moon.
Yes — about 2.6 times higher. Mars gravity is 38% of Earth's, so the same leg force produces a higher jump.
Pluto is classified as a dwarf planet since 2006. We include it because it remains a popular target of curiosity, and its extremely low gravity (0.62 m/s²) provides an interesting comparison.
No — they are in freefall (constantly falling around Earth), creating the sensation of weightlessness. Actual gravity at ISS altitude (~400 km) is still about 89% of surface gravity.
