The rings of Saturn are made up of icy objects ranging in sizing from one particular centimetre to hundreds of metres, Every of which happens to be By itself orbit concerning the planet. Therefore, a specific amount of Saturnian moons can not be specified, as there isn't any objective boundary among the many modest anonymous objects that form Saturn's ring method as well as the greater objects which have been named as moons.

Images unveiled a tiny moon, later on named Dactyl. Astronomers have given that Found greater than 450 moons orbiting the asteroids and trans-Neptunian objects.
Europa could be the photo voltaic system’s smoothest item, suggesting its floor is remade by inside procedures extra frequently than most other worlds Apart from Earth.
Planets circle the Sunlight; moons circle the things which circle the Sunlight—planets, dwarf planets, along with other so-referred to as tiny photo voltaic program bodies. Normally, moons are various and intriguing worlds unto their own.
Saturn also has hundreds to Countless moonlets embedded in its ring procedure. Moons are outlined by measurement. See also Moons of Saturn to get a-Z checklist and points.
