Some asteroids do in fact have moons. The asteroid Ida has a moon, Dactyl, which was found when the space probe Galileo flew past on the way to Jupiter. Two asteroids that are roughly the same mass would be a binary asteroid, while a large disparity in mass means the smaller one is a moon of the larger one.
