Here's a theoretical paper that asks an interesting question: When the solar system was very young and still very hot, could medium-sized asteroids have been habitable abodes for life?

Since the Galileo mission discovered tiny Dactyl circling Ida in 1993, quite a lot of asteroid systems have been found to be binary; there are even a few triples. So it's quite reasonable to guess that two of the biggest asteroids, Ceres and Vesta, might also have satellites.
