Earth’s Second Moon

I just found out Earth has a second moon, called Cruithne. There may be a third, but most people think it’s space junk. And according to this paper, there are two more asteroids in “resonant orbits”. But unfortunately they are called 1998 UP1 and 2000 PH5. Unless and until they come up with some cool Celtic names for these, they aren’t going to get much PR.
