Welcome to You Ask Andy

Debbie Mrochuk, age l3., of Winnipeg Man,, Canada for her question:

How high can a man jump on the planet pluto?

We earthlings are used to the gravity of our home planet: our muscles are built to walks rung jump and leap on its surface. The force of surface gravity is different on each of the planets and our earth trained muscles would seem to work differently. Suppose a spaceman could jump 4 feet on earth. On little mercury his earth trained muscles could leap l6 feet and on giant Jupiter only about l foot.

The planet pluto is on the outer rim of the solar system and very far from earth. If they prove true, then Pluto's  Surface Gravity:(0.06 x Earth's)   In this case an earthman could jump about twice  higher, than he can on his home planet.  The following are Pluto’s statistics
