Saturn's

The mean radius of Saturn's moon Titan is a factor of 0.404 of Earth's.

Saturn's atmosphere has winds which can blow at over 1800 kilometers per hour.

Scientists believe that the particles in Saturn's rings came from the destruction of moons circling the planet. As comets and meteorites smashed the moons, Saturn's gravitational pull shaped the particles into rings.

The thickness of Saturn's rings ranges from 10 to 100 meters and the rings vary in brightness.

Astronomers believe Saturn's rings developed from particles that resulted from the break-up of naturally occurring satellites.

The discovery of Saturn's mysterious ring system led to a rush of observations of the planet during Huygens' time.

Saturn's rings stand out because they are very bright and contain lots of material. Their brightness is due to their makeup. The rings are made of icy material that reflects sunlight, just as ice does on Earth.

Saturn's ring system is about 175,000 miles (280,000 km) across, yet only about half a mile (1 km) thick.

Compared with Saturn's size, the rings appear paper-thin.

Titan, Saturn's largest moon, has rain that is made up of frigid liquid methane, hitting a bitterly cold surface, where the temperature is minus 290 degrees Fahrenheit.
