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

  1. 1Enter a weight and choose kilograms or pounds.
  2. 2Compare what a scale would read and how strong gravity is across nine worlds.
  3. 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.
