Q:

How can planets rotate around planets and not get destroyed by space debris?

A:

Planets rotate around other planets or objects due to gravity, however sometimes space debris hits planets and knocks them off orbit. Planets always have a chance of being hit by something else in space and being knocked around. For example, the Moon is a natural satellite that was created when Earth was hit by something in space. The Moon was a part of the Earth, but was broken off when this collision occurred. For a planet to be destroyed, broken, or knocked off its orbit it must be hit with something large enough and going fast enough to overcome its own mass and pull towards its sun.
