The early Earth had two moons instead of just one — our familiar moon, as well as a smaller companion moon that also rose and set in the sky for tens of millions of years.
That's according to a new theory that says this smaller moon eventually went careening into our moon and is still there, in the form of mountains on its far side. (http://www.npr.org/2011/08/03/138954932/early-earth-may-have-been-orbited-by-two-moons?sc=fb&cc=fp)
