MSNBC is carrying this article detailing the discovery of a pair of "dancing asteroids". One is about a mile wide and not much more than a pile of rubble held together with gravity, the other is about a quarter that size and solid. Both rotate about each other, with the gravity of each affecting the other each turn. The larger of the pair, "Alpha", is also spinning so fast it's close to flying apart.

Ain't space science grand?
