A lot of them are quite small. 7 moons are big enough to become in hydrostatic equilibrium, like Titan, moons the next largest moon while in the Photo voltaic Procedure. Including these large moons, 24 of Saturn's moons are common, and customarily named just after Titans or other figures affiliated with the mythological Saturn.
