Last Answer : The moon is in the exact right area to be captured by the Earths gravity. Not to close and not to far. Well it actualy IS a little too close. The moon is in a slightly degrading orbit. ... because something that is ejected from the Earth doesn't establish orbit by itself. It needs an outside force.
