When I was a kid, we were taught Jupiter had 13 moons. Now I just learned from watching season 2 of The Expanse that it has 79 moons. Checking a Wikipedia article, it has closer to 600 natural satellites ranging in diameter from 5300 km for Ganymede to a few meters for most. It is basically surrounded by its own asteroid belt.

  It's thought most of the small ones were created by larger ones colliding with each other, but not losing their orbit.
