Moons - space.com

Pictures available at this page are showing mostly "planetary satellites". Some of these satellites are bigger than Mercury (the smallest "planet"). Because they are called "moons" and not planets, they are never featured preminently in any astronomy encyclopedia. Yet, if they were not orbiting other planets, they would not be called moons but rocky planets or ice planets.
