I am the very last space blogger in the universe to post about this video, but that doesn't make it any less cool.

253 Mathilde is the largest asteroid that has ever been visited by a spacecraft. It's held that distinction for more than twelve years, but next year it'll be upstaged by the considerably larger 21 Lutetia, which Rosetta will fly by on July 10.
