Saturn

Quick Facts 1. Saturns greek god is Cronus the god of agriculture. 2. Saturn is the root of the English word Saturday 3. Saturn is 75% Hydrogen and 25% Helium 4. It is also the least dense planet less than water meaning if it was put in water instead of sinking to the bottom it would flout. 5. Has about 61 moons 6. 4 main rings and 3 fainter rings



Saturn was first visited by NASA's Pioneer 11 then came Voyager 1 and Voyager 2. On July 1, 2004 Cassini was sent to orbit Saturn for at least four years. Sun is very hot its (12000 K at the core) it radiates more energy into space than it gets from the sun. Winds on Saturn is up to 500 meters per second. The wind plus the heat is what gives Saturn its orange and yellow color.

__Saturn's Moons__ Titan-** Discovered in 1655 by Christiaan Huygens. Its a cold world enclosed in by a haze atmosphere impenetrable by telescopes and cameras. Titan has a equatoral radius of 1600 miles, that makes it the second largest moon in the solar system
 * Mimas-**Was discovered by William Herschel in 1789. Looks like a bull's eye from a angle. This moon has a 88 mile crater called the Herschel Crater. Miamas is one of Saturn's inner moons with a 246 mile diameter.
 * Enceladus-** Enceladus is one of the innermost moons of Saturn. It is about the same size as Mimas but has a smoother, brighter surface. The problem about Enceladus is that it reflects almost 100 percent of its sunlight. Because of this Enceladus is only -330 degrees.
 * Tethys-** Is a small moon at 662 miles in diameter. Tethys has many craters. But its main two scares are a giant impact and a great valley. the crater is called Odysseus Crater and the valley is Ithaca Chasma.
 * Dione-** Is about 698 miles in diameter. It orbits Saturn every 2.7 days at a distance 234,000 miles roughly the same as the moon orbits Earth. Dione is heavily cratered with craters as big as 62 miles across.
 * Rhea-** Rhea is the second largest moon orbiting Saturn with a diameter of 949 miles. It is a small, cold, airless body and is only -281 degrees Fahrenheit. Rhea was only seen as a little dot until Voyager 1 and 2 were sent.
