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.

Earth
70.0 kg

Gravity: 1.00 (reference)

Mercury
26.6 kg
Gravity: 0.3802.6x lighter

On Mercury, a single day lasts longer than a whole year!

Venus
63.7 kg
Gravity: 0.9101.1x lighter

Venus spins in the opposite direction compared to most other planets.

Moon
11.6 kg
Gravity: 0.1666.0x lighter

You could jump 6 times higher on the Moon than on Earth.

Mars
26.6 kg
Gravity: 0.3802.6x lighter

Mars is home to Olympus Mons, the tallest volcano in the solar system (21 km high).

Jupiter
163.8 kg
Gravity: 2.3402.3x heavier

Jupiter is so massive it could fit 1,300 Earths inside it.

Saturn
74.2 kg
Gravity: 1.0601.1x heavier

Saturn is so light it would float in a giant bathtub!

Uranus
64.4 kg
Gravity: 0.9201.1x lighter

Uranus is tilted at 98°: it literally rolls along its orbit.

Neptune
83.3 kg
Gravity: 1.1901.2x heavier

Winds on Neptune reach 2,100 km/h, the fastest in the solar system.

Pluto
4.4 kg
Gravity: 0.06315.9x lighter

On Pluto, you would weigh barely more than a house cat!

Sun
1953.0 kg
Gravity: 27.90027.9x heavier

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.
