Moon, Cruithne, J002E2?

The discovery of a third satellite of Earth has been reported by BBC news and Ananova. Alternatively, it might just be a bit of discarded rocket casing. In any case, the amateur astronomer who found it, Bill Yeung, will probably get a lot of attention for this: a geocities.com homepage which appears to belong to him has been shut down for being beyond its transfer limit. Whether it's a newly captured asteroid, or just a bit of space debris, I'll be keeping track of the story on my own J002E2 page.
