What do you weigh on other planets?
Type your weight and see what the scale would read on nine worlds, and how high you could jump on each one.
Mercury
11 kg
0.38× Earth · lighter than on Earth
jump 1.1 m
Small and rocky, so it barely holds on to you.
Venus
27 kg
0.90× Earth · lighter than on Earth
jump 44 cm
Almost exactly Earth's size, so almost exactly Earth's pull.
Earth
you are here
30 kg
1.00× Earth
jump 40 cm
Home. Everything here is measured against this one.
The Moon
5.1 kg
0.17× Earth · lighter than on Earth
jump 2.4 m
The astronauts bunny-hopped because walking normally was harder than jumping.
Mars
11 kg
0.38× Earth · lighter than on Earth
jump 1.1 m
The same pull as Mercury, from a planet nearly three times wider.
Jupiter
76 kg
2.53× Earth · heavier than on Earth
jump 16 cm · no solid ground
There is no ground here. This is the pull at the top of the clouds.
Saturn
32 kg
1.06× Earth · heavier than on Earth
jump 38 cm · no solid ground
A hair more than Earth, even though Saturn is the least dense planet of all.
Uranus
27 kg
0.90× Earth · lighter than on Earth
jump 44 cm · no solid ground
A giant that pulls slightly less than Earth, because you would be so far from its centre.
Neptune
34 kg
1.14× Earth · heavier than on Earth
jump 35 cm · no solid ground
The strongest pull of any planet except Jupiter.
Your body never changes. What changes is how hard each world pulls on it, which is what a bathroom scale actually measures. Scientists say your mass stays the same while your weight changes.
Jump heights assume a standing jump of 40 cm on Earth, which is about right for a child.
How to use this tool
- 1Enter a weight and choose kilograms or pounds.
- 2Compare what a scale would read and how strong gravity is across nine worlds.
- 3Open the extra worlds to compare jump estimates and places with no solid surface.
What you can learn
- Your mass stays the same while your weight depends on the gravity of each world.
- A large planet does not always pull harder because its radius also matters.
- Gas giants have no solid ground, so their quoted gravity is measured near the cloud tops.
