Rotational and Orbital Periods
As seen from above the north pole of the Earth, most of the planets and satellites revolve in an anticlockwise direction. This is called Direct Rotation. Some satellites revolve in a clockwise sense. This is called Retrograde Rotation and is shown by the presence of a minus sign. Phoebe revolves in the retrograde direction.

Iapetus has one very dark side and one bright side; probably the result of a collision.
The satellites of Saturn have names associated with classical Greek mythology.
Titan is one of the largest satellites in the Solar System. It is larger than the planet Mercury. Most of the other 17 satellites are irregularly shaped bodies; only three are over 1000km in diameter. Four new satelites have been discovered in October 2000. Little is known about them as yet.
Some of the satellites of Saturn are bunched together. The inner ones are very close to the planet's ring system. Phoebe is more distant than the others. It is probably a captured asteroid.
About half of Saturn's satellites rotate in the same period as they revolve around the planet. This is caused by the strong tidal forces exerted by the planet on the satellite. The outer satellites are less affected by tidal forces.
This is the angle of inclination of the satellite orbits compared to the planet's equatorial plane. Most of Saturn's satellites orbit very close to the planet's equator. The outer two satellites are the exceptions.
The orbits of Saturns's satellites are nearly circular. The exceptions are Hyperion and Phoebe.
This is the percentage of sunlight that is reflected by the satellites. Saturn's satellites tend to be very reflective. They are probably icy bodies.
