How high you'd jump
With the same leg power, your 50 cm jump on Earth becomes 301 cm on the Moon and 133 cm on Mars.

How weight changes between worlds
Your mass never changes, but weight is mass times surface gravity. Each world pulls differently, so a scale calibrated for Earth reads your mass multiplied by that world's gravity relative to Earth's.
Jump height scales the other way: with the same take-off speed you reach a height of roughly one divided by gravity, so low-gravity worlds let you soar.
Where do the gravity numbers come from?
From NASA's planetary fact sheets, which list each body's surface gravity as a ratio to Earth's.
Why would I weigh more on the Sun?
The Sun's surface gravity is about 28 times Earth's, so the same mass presses on a scale about 28 times harder. (You could not actually stand there.)
Is the jump height exact?
It is an idealised estimate assuming the same launch speed and ignoring air, suits and terrain — a fun comparison rather than a mission spec.
About this calculator
This calculator shows what you would weigh on every major body in the solar system — the Moon, Mars, Jupiter, the Sun, and more. Your mass never changes, but weight depends on surface gravity, so the same body feels lighter on Mars and crushingly heavy near the Sun. Enter your Earth weight and see the full comparison instantly.
How to read your results
The headline shows your weight on the Moon — one of the most popular reference points. Below it, a horizontal bar chart lists all 11 bodies sorted from heaviest to lightest, with bar width proportional to the Sun (the strongest gravity). Each row shows the scale reading you would get if you stood there with an Earth-calibrated scale. The jump-height section tells you how high the same standing jump would send you on each body, using your Earth jump height as the baseline.
Worked example
A person weighing 70 kg on Earth with a 50 cm standing jump — what does each body show?
On the Moon they register 11.62 kg and jump 301.2 cm. On Mars the scale reads 26.39 kg and the jump reaches 132.6 cm. Jupiter shows 165.20 kg (jump 21.2 cm). The Sun would register 1,953 kg. Pluto shows just 4.97 kg with a jump of 704.2 cm — over 7 metres.
Frequently asked questions
What is the difference between mass and weight?
Mass is the amount of matter in your body, measured in kilograms (or pounds of mass), and it does not change wherever you go. Weight is the force gravity exerts on that mass — it is mass multiplied by the local gravitational acceleration. A 70 kg person always has a mass of 70 kg, but their weight on Mars is only about 26 kg-equivalent because Mars pulls with 37.7% of Earth's gravity.
Why does the Sun have such extreme gravity?
Surface gravity depends on a body's mass divided by the square of its radius. The Sun contains over 99.8% of the solar system's total mass, which overwhelms its large radius. Its surface gravity is roughly 27.9 times Earth's, so a 70 kg person would register nearly 1,953 kg on a scale there — ignoring the fact that no solid surface exists.
How is jump height calculated?
For a constant take-off velocity (same leg effort), jump height scales inversely with surface gravity: height = Earth_jump / gravity_ratio. On the Moon (gravity ratio 0.166) a 50 cm Earth jump becomes about 301 cm — roughly 3 metres. On Jupiter (2.36×) the same jump only reaches about 21 cm.
Are Pluto and the Moon really planets?
Pluto is classified as a dwarf planet by the IAU since 2006, and the Moon is Earth's natural satellite, not a planet. They are included here because they are popular reference points and the gravity data from NASA's fact sheets is well established.
Does atmosphere or rotation affect these figures?
The calculator uses NASA's tabulated surface-gravity ratios, which are derived from measured mass and radius and do not include centrifugal effects from rotation or atmospheric pressure. For everyday curiosity the difference is negligible, but precise mission planning would require more detailed models.
How it's calculated
Weight on each body is computed as: weight = earthWeightKg × gravityRatio, where gravityRatio is the ratio of that body's surface gravitational acceleration to Earth's (9.8 m/s²). Gravity ratios come from the NASA NSSDCA Planetary Fact Sheet (https://nssdc.gsfc.nasa.gov/planetary/factsheet/planet_table_ratio.html) for the eight planets plus the Moon and Pluto, and from the NASA Sun Fact Sheet (https://nssdc.gsfc.nasa.gov/planetary/factsheet/sunfact.html) for the Sun (274 m/s² → ratio 27.9). Jump height on each body is earthJumpCm / gravityRatio, assuming constant take-off kinetic energy so that peak height is inversely proportional to local gravity.
