Saturn
probably holds the distinction of the most attractive planet (well, next
to Earth!) because of its amazing rings that circle it. The rings
are of ice or ice-covered particles, and although they stretch out vast
distances from the planet, they are only thin. Like Jupiter, Saturn
is a "gas giant" with lower density than Earth. Saturn has at least
28 moons, the largest one being Titan, which has an atmosphere and water.
A spacecraft called Cassini left earth in 1997 and will send a probe to
Titan in 2004.
