Our spacecraft is getting closer to Saturn now. Saturn is the sixth planet from the Sun. It is so far away that it has taken us six years to get here from Earth. We are traveling as fast as the Pioneer 11 spacecraft - more than 100,000 mph!


Saturn is a strange looking planet. It has rings. It isn't the only planet with rings. Jupiter, Uranus, and Neptune have rings, too. Their rings aren't nearly as big or as bright as Saturn's, though.


Saturn's rings are formed of pieces of ice. Some of the pieces are as small as grains of sand. Some are as large as a house. No one knows for sure how Saturn's rings formed. It may have had something to do with Saturn's moons.
