Enter your weight. Find out what you'd weigh on Jupiter, the Moon, or a neutron star.
Weight equals mass multiplied by surface gravity. Earth's gravity is 9.8 m/s². Jupiter's is 24.8 — about 2.5 times stronger. A neutron star's surface gravity is roughly 2×10¹² m/s², which means a 70 kg human would weigh about 140 billion kilograms. The gravitational force would tear your body apart long before you touched the surface.
These calculations use surface gravity data from NASA's planetary fact sheets. The Moon's gravity is 1.62 m/s², Mars is 3.71, and Io (Jupiter's volcanic moon) is 1.80. If you could stand on the surface of a neutron star, you would be crushed into a layer of material about 1 millimeter thick — a pancake made of atoms.
The reason gravity varies so much has to do with both mass and radius. A planet like Jupiter is huge but less dense than Earth. A neutron star is tiny — about 20 km across — but contains more mass than the Sun. That concentration of mass in a small radius is what creates the insane gravity.
Jupiter has 318 times Earth's mass, so its surface gravity is 2.5x stronger. Weight = mass × gravity, so you feel heavier.
No. Jupiter is a gas giant with no solid surface. The "surface gravity" is measured at the cloud tops.
A neutron star has about 1.4 solar masses packed into a sphere ~20 km wide. A teaspoon of its material weighs ~4 billion tons.
