How high a human being could jump on different worlds in the solar system.

Anything that makes you leave the ground on Phobos, goodbye 👋

Phobos gives you the power to land somewhere else! well, which one do you find interesting? 😄

Interesting Fact 🚨 if you were to jump on smaller and less dense planets, you might not come back down, but jump out into space! 😶‍🌫️😂

Meanwhile on the moon.

Basketball in our solar system clearly better in some places!

On a low gravity world, one might be tempted to jump just as high as you can (which is okay by itself)—but then expect, after soaring above everyone's heads, to come back down lightly on just your tippy-toes. If you try it, however, with such an expectation—you'll likely break your ankles! This is because you'll actually land (naively speaking) with exactly the same impact force as an otherwise identical upwards leap (the mightiest jump you're capable of) would experience on earth. No tippy-toe returns to earth in that case! Less naively, on one's return to “earth” after jumping high up on a low-gravity world (when you do make it back down, that is—which could take a while), the impact then will be even _more forceful_ than one would experience following an equally energetic jump on earth—because earth's (much) higher gravity subtracts from the force you can put into your jump (i.e., on earth 1 g of effort doesn't move you off the ground at all). Moreover, you'd better carefully keep your stance and orientation while soaring (for a much longer period of time) over everybody's heads, or you could crash with a belly flop (or worse, on your head!) rather than landing safely with your legs—while being careful of those ankles!
