Discover what you would weigh on every planet in the solar system, the Moon, the Sun, and even on a neutron star. Your mass stays constant throughout the universe, but weight — the force gravity exerts on that mass — changes dramatically depending on which world you are standing on.
On the Moon, you would weigh just 16.6 percent of your Earth weight — light enough to jump over a car. On Jupiter, you would weigh 2.5 times more than on Earth and struggle to lift your own arm. On a neutron star, the gravity is 200 billion times Earth's — a marshmallow would hit the surface with the force of a nuclear bomb.
Enter your weight in pounds or kilograms and see it calculated for Mercury, Venus, Earth, the Moon, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto, the Sun, and a neutron star. Each result includes a percentage comparison, a visual bar, and a fun fact about that world. This free tool runs entirely in your browser.
