Take a moment to jump straight up and down... Go ahead, we'll wait.
How high was your jump? And how long did it last?
On Earth, a good leap can clear over half a meter (1.6 feet) in a second. But hop with the same force elsewhere in the solar system — some place like the moon, Mars, or even a comet — and all bets are off, due to the different masses of those worlds.
Thankfully, astronomers Stuart Lowe and Chris North have crunched the numbers on jump height across different celestial bodies with an interactive browser app, called High Jump.
Their app highlights the effects of wildly different gravitational fields. It's simple, educational — and weirdly addictive.
Here's how high and how long an earthly jump would play out on other worlds.

This is a normal vertical hop for a person on Earth. The bottom of your feet might break 1.5 feet and the whole jump would last a second.
On to the moon: the only place other than Earth where humans have dared to leap.
