Size of the Earth compared to Saturn

A Hubble Space Telescope image of the planet Saturn

Saturn has 18 known Moons (satellites), more than any other planet.  There may very well be several small ones yet to be discovered.  It's large ring system was created by a Moon that got too close to Saturn and was pulled apart by the planets gravity.  The remaining particles continue to break up into smaller and smaller particles that orbit the planet saturn.

Saturn is the 6th planet from the sun.  Its distance is 9.5 times further from the Sun than Earth's
distance the Sun.  Saturn takes 29 years and 167 days to make one complete revolution around the Sun.  Although Saturn weighs a lot more than Earth, it's density is less than water which means that if you had a big enough bath tub, you could float Saturn in it!

Of those moons for which rotation rates are known, all but Phoebe and Hyperion rotate synchronously.
The three pairs Mimas-Tethys, Enceladus-Dione and Titan-Hyperion interact gravitationally in such a way as to
maintain stable relationships between their orbits:
The period of Mimas' orbit is exactly half that of Tethys, they are thus said to be in a 1:2 resonance;
Enceladus-Dione are also 1:2; Titan-Hyperion are in a 3:4 resonance.
In addition to the 18 named satellites, at least a dozen more have been reported and given provisional designations.
