SUMMARY: 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)

Very interesting. I must admit I didn't know we had a second moon, let alone a third.

It depends on how you define "moon." Here's some info on the "second moon":

I've wondered if Cruithne, and the other co-orbitals (how many are known or suspected now?), preclude Earth trojans.

Was it in fact not J002E2 but J002E3?

That mysterious object discovered in orbit around Earth on September 3 is likely not to hit the Moon. Rather, the suspected Saturn IVB upper stage will swing back into orbit around the Sun, scientists said today.

A study of the path of the object -- dubbed J002E3 -- has led to the new assessment, said Paul Chodas of the NASA Jet Propulsion Laboratory (JPL) in Pasadena, California.
[...]
Tracking and space-debris experts contend the object is likely an Apollo lunar leftover, due to its small size and odd orbit. They're pretty sure it's an old Saturn S-IVB upper stage used to hurl Apollo 12 astronauts to the Moon in late 1969.

I want those second and third moons captured.
