Your Weight on Other Planets
How heavy would you be across the solar system?
Find out how much you would weigh on every planet, the Moon, Pluto, and even the Sun. Gravity varies enormously across the solar system — you'd weigh just 16% of your Earth weight on the Moon, but over 250% on Jupiter. Enter your weight in kg or lbs, then instantly see your equivalent weight across all solar system bodies, ranked from lightest to heaviest.
💡 On Jupiter's surface (if it had one), you'd weigh about 2.5 times more than on Earth — but on Mars, you'd feel as light as a feather at just 38% of Earth gravity.

Frequently asked questions
How much would I weigh on Mars?
On Mars you weigh about 38% of your Earth weight — a 70 kg person weighs the equivalent of 26.6 kg. That is because Mars has 38% of Earth's surface gravity (3.71 m/s² vs. 9.81 m/s²). Astronauts on a future Mars mission would feel noticeably lighter and could jump roughly 2.6 times higher.
How much would I weigh on Jupiter?
Jupiter has the strongest surface gravity of any solar system planet at 24.79 m/s² — about 2.53 times Earth's. A 70 kg human would weigh the equivalent of 177 kg. (Jupiter has no real surface, so this is the gravity at its 1-bar cloud-top altitude.)
What is the difference between mass and weight?
Mass is the amount of matter in your body, measured in kilograms — it stays constant everywhere in the universe. Weight is the gravitational force acting on that mass, measured in newtons or pounds-force. Your weight changes from planet to planet, but your mass does not.
How much would I weigh on the Sun?
The Sun's surface gravity is 274 m/s² — about 28 times Earth's. A 70 kg human would weigh the equivalent of 1,960 kg, or roughly two tonnes. (You would also be vaporised at 5,500°C, so this is purely theoretical.)
