Earth's Third Moon Discovered

An amateur astronomer has discovered what could be a new object orbiting the Earth; maybe it's a recently captured space rock, or maybe it's just a remnant from the Apollo program. Whatever it is, the object, dubbed J002E2, seems to orbit the Earth every 50-days in a wide orbit. If it turns out to be natural, the object will become the Earth's 3rd moon (and you only thought we had one), after Cruithne which was discovered in 1986 in a long erratic orbit. (BBC News Story)
