  1. Saturn The Ringed Marvel By Roger Pence Per. 1

  2. Saturn Facts: Distance from Sun: 856 million miles Size compared to Earth: Density: 0.6 g/cubic centimeter (would float in water!) Composition: 97% Hydrogen, 3% Helium Orbital Year: 29.5 years Period of Rotation: 10 hours 39 minutes Planetary Symbol

  3. The Rings  A ring Thin outer Mainly ice and Small particles C ring B ring

  4. The Gas Giant Saturn's atmosphere is almost entirely hydrogen and helium. Voyager 1 found that about 7 percent of the volume of Saturn's upper atmosphere is helium (compared with 11 percent of Jupiter's atmosphere), while almost all the rest is hydrogen.

  5. Saturn’s moons These are just five of Saturn’s 40 or more moons

  6. Saturn’s Earthly Visitors Voyager 1 carried the “Golden Record” of what life on Earth is like First visited by Pioneer 11 in early 1979, Voyager 1 and 2: Fly-by Saturn in 1979 and 1980

  7. A day in the life of Saturn Winds blow at high speeds in Saturn. Near the equator, the Voyagers measured winds about 500 meters a second (1,100 miles an hour). The wind blows mostly in an easterly direction. Strongest winds are found near the equator, and velocity falls off uniformly at higher latitudes. At latitudes greater than 35 degrees, winds alternate east and west as latitude increases.

  8. Colonization challenges No solid surface to stand on (it’s a gas planet!) Very cold Very windy Very short days Long years Little usable sunshine No breathable atmosphere Signal takes to reach Earth (conversation with Earthlings difficult!)

  9. What’s planned? 2008: European Space Agency probe Cassini-Huygens will closely monitor Saturn’s moon Titan

  10. What questions are yet unanswered? • How does Saturn generate its internal heat? • What are the "spokes" in the rings? • What is the origin of the rings?
