Saturn

by Justin

Saturn is the sixth planet from the Sun and the second largest planet. Saturn has eighteen moons. It takes 29 years for it to make a whole revolution. It takes ten hours for Saturn to rotate. Saturn has been known since prehistoric times. Saturn was first visited by Pioneer 11 and

later by Voyager 1 and Voyager 2. Early observations of Saturn were complicated by the fact that the earth passes through the plane of Saturn's rings every few years. Saturn moves in it's own orbit. It was not until 1659 that Christian Huygens correctly figured out the geometry of the rings.
