They must mean Earth’s *other* other moon. I knew there was a second one with a name (Cruithne) instead of a letter number deal...

Cruithne never has a geocentric eccentricy less than one, so it’s not actually in orbit around the Earth. It is in an odd sort of resonance with the Earth. Check out the Wikipedia article. http://en.wikipedia.org/wiki/3753_Cruithne
So what ever became of J002E3?
Is it or is it not a moon?
