Answer 2

Answer:

The moon is constantly falling on earth.

One think you will learn when you study revolution of celestial bodies is that orbiting is nothing but falling but missing the ground.

As to why it's not coming any closer, that's because it has the speed of 3683 kmph (Google), which is so fast, it generates a centripetal force (when you spin an object tied to a thread, it tends to move out, that's because of the same force). This force cancels the gravitational force and the object stays at the same radius.
