# On the moon how high would you have to jump to the point were you just flew away?

56 thousand kilometers. That's the size of the Moon's Hill sphere. You don't need to reach escape velocity because you don't have to escape from the Moon's gravity, you only have to get far enough to pass beyond the Moon's Hill sphere. Get past that and the gravity of other bodies is stronger than that of the Moon. Mind you, the difference between the Moon's escape velocity and the near instantaneous velocity you'd need to jump 56,000 km straight up is less than a dozen m/s.

Impossible. The Moon's gravitational acceleration. Is 1/6 Earth's,  but no human could reach escape victory from the Moon .

How high you jump would not matter.

You would need to attain escape velocity.

During Apollo flights, just to get back into Lunar orbit, the Ascent Stage of the LM had to go from zero MPH on the surface up to 3,000 MPH.

The only astronomical bodies from which you could reach escape velocity just by jumping would be very, very small asteroids.

Altitude would not matter

It is Escape Velocity

On the Moon it is 5, 300 mph

Earth's 17, 500 mph

It's not altitude... it's speed.  You can be motionless, and 1,000 miles high over the moon - it's gravity is going to pull you down.  But, if you could jump with a speed of about 5,300 mph from it's surface - you'd have escape velocity, and would never return.

I dont know, my guess is about 30 feet.

I dont think it's possible for a human. I heard that you can jump so high that you will break your legs when you land.
