Surface gravity

# Weight on other planets

Step on a bathroom scale on the Moon and it reads about a sixth of what it does at home; on Jupiter's cloud tops, well over double. Enter what you weigh on Earth to see the reading on every world.

## Mass stays, weight changes

Your mass, the amount of you, is the same everywhere. Weight is the pull of gravity on that mass, and a bathroom scale is calibrated for Earth's pull. So the reading on another world is your Earth reading multiplied by that world's surface gravity compared with Earth's: 70 kg × 0.377 = 26.4 kg on Mars.

The ratios are NASA's figures for gravity at the equator, including the small outward push from each planet's spin. Jupiter, Saturn, Uranus and Neptune have no solid surface, so their gravity is given at the level where air pressure equals one Earth atmosphere (1 bar), roughly the cloud tops. The Sun's figure is for its visible surface.

The **Force** column turns the reading into newtons using standard gravity, 9.80665 m/s². The **Same jump** column assumes you push off just as hard, so the height grows as gravity shrinks; a spacesuit and a thin atmosphere would change that in real life.

## Questions and answers

**Why do Mercury and Mars have almost the same gravity?**

Mars has about twice Mercury's mass, but Mercury is much denser, with a large iron core, so its surface sits closer to its centre. Being closer makes up for the smaller mass, and both pull at about 0.38 times Earth's gravity.

**Why is Saturn's gravity lower than Earth's?**

Saturn is 95 times more massive than Earth, but its cloud tops are about nine Earth radii from its centre. Gravity weakens with the square of distance, which almost cancels the extra mass, leaving 0.916 times Earth's pull.

**Could I really stand on Jupiter?**

No. There is no solid ground, only deeper and denser gas and liquid. The Jupiter figure is what a scale would read while floating at the 1 bar level, which is useful for comparison but not a place you could visit.

**Does this work in pounds?**

Yes. Choose lb and the readings and jump heights switch to pounds and inches. The ratios are the same in any unit.
