More Facts

• In 1610, Italian astronomer Galileo Galilei was the first to gaze at Saturn through a telescope.

• In 1659, Dutch astronomer Christiaan Huygens, using a more powerful telescope than Galileo's, proposed that Saturn was surrounded by a thin, flat ring.

• Distance from the Sun:  1,426,725,400 km• While the other three gas planets in the solar

system - Jupiter, Uranus and Neptune - have rings orbiting around them, Saturn's are by far the largest and most spectacular.

Even more facts!

• Missions : Pioneer 11, Voyager 1 and 2 and Cassini-Huygens

• Saturn is not a sphere• Saturn is the root of the English word

"Saturday“• Saturn is in the outer solar system

Interesting bit’s of info

• You can see Saturn at night with the naked eye and it is easy to identify because it doesn't "twinkle" like stars do.

• Saturn is named after the roman god of agriculture.

• Titan, Saturn's largest and the Solar System's second largest moon (after Jupiter's Ganymede), is larger than the planet Mercury and is the only moon in the Solar System to possess a significant atmosphere.
