Planetary Weight Calculator
Find out how much you would weigh on every planet in the solar system, on the Moon, and on the Sun. Enter your Earth weight and explore the gravity of each celestial body.
Gravity: 1.00 (reference)
On Mercury, a single day lasts longer than a whole year!
Venus spins in the opposite direction compared to most other planets.
You could jump 6 times higher on the Moon than on Earth.
Mars is home to Olympus Mons, the tallest volcano in the solar system (21 km high).
Jupiter is so massive it could fit 1,300 Earths inside it.
Saturn is so light it would float in a giant bathtub!
Uranus is tilted at 98°: it literally rolls along its orbit.
Winds on Neptune reach 2,100 km/h, the fastest in the solar system.
On Pluto, you would weigh barely more than a house cat!
On the Sun, you would be crushed by gravity 28 times stronger than Earth's.
How does it work?
Your mass stays the same everywhere in the universe (70 kg). What changes is your weight, which depends on the local gravity.
Weight is calculated as follows: Weight = Mass x Relative gravity
For example, on Mars: 70 kg x 0.38 = 26.6 kg
Did you know?
With a mass of 70 kg, you would weigh only 4.4 kg on Pluto — barely the weight of a house cat! Conversely, on the Sun, you would weigh 1953 kg. It would take 28 people to match your solar weight on Earth.
