"In 95 years, the asteroid will have advanced all the way around to where it is catching up to Earth from behind. A similar interaction will then push the asteroid back onto a slower outside track, and the pattern will repeat. In about 600 years, the asteroid may begin looping around Earth like a tiny, distant quasi-moon."
I've hear it suggested that this astroid was a moon to Earth and created the light that the wise men followed 200 years ago.
