. Is there a force that keeps them in a specific distance from each-other or they will pull each-other for a long time until they maybe crash??


Two forces

1. Gravity = pulling at each other
2. Centrifugal force = trying to move away from each other

Keeps them at a safe distance.

BTW
The moon is slowly moving away from the earth. So in the far future it will be significantly farther from earth than it is now.
