Saturn is big -- the second largest planet in the Solar System, with huge globe-girdling rings and 18 moons.

Saturn's largest moon, Titan, is the second-largest moon anywhere in the Solar System. Other moons of Saturn are Rhea, Iapetus, Dione, Tethys, Enceladus, Mimas, Hyperion, Prometheus, Pandora, Phoebe, Janus, Epimetheus, Helene, Telesto, Calypso, Atlas, and Pan, plus some small unseen shepherd moons.

Cassini. NASA and the European Space Agency (ESA) have sent the Cassini probe to a 2002 rendezvous with the planet Saturn. Cassini will drop a probe, named Huygens, into Titan's atmosphere. Huygens will drop to a soft landing on Titan's surface. Scientists hope that impact will allow analysis of soil or whatever's on the surface before the probe dies.

After the end of the Huygens part of the mission, Cassini will spend four years circling Saturn 30 times, sometimes as low as 600 miles above the colossal planet's surface.
