Frequently asked questions

Why would I weigh less on Mars?

Mars has about 38 percent of Earth's surface gravity, so you weigh roughly a third of your Earth weight. Your mass stays exactly the same.

Why does my age change on other planets?

A planet's year is the time it takes to circle the sun. Mercury's year is short, so you would be older there, while Neptune's is very long, so you would be a baby in years.

Is the weight shown really my mass?

No, your mass stays the same everywhere. The tool shows the weight a scale would read under that planet's gravity, so only the pull on you changes.
