Saturn By Olivia Modi & Sebastian Santos

Saturn has been known since prehistoric times. Saturn was first visited by NASA's Pioneer 11 in 1979 and later by Voyager 1 and Voyager 2. Cassini (a joint NASA / ESA project) arrived on July 1, 2004 and will orbit Saturn for at least four yearsPioneer 11Voyager 1Voyager 2 Cassini. Saturn’s Informason

Planet Facts Saturn is the 6 th planet to the sun. Distance from the sun Average distance from Sun AU (1,426,725,400 km) Movement from orbit-time needed to revolve around the sun distense from the sun Time needed to rotate on axis Moons -34 Earth's, because Saturn is so far from the sun. The temperature at the top of Saturn's clouds averages -285 degrees F (-175 degrees C). Titan, has a diameter of about 3,200 miles (5,150 kilometers) -- larger than the planets Mercury and Pluto. Titan is one of the few satellites in the solar system known to have an atmosphere. Its atmosphere consists largely of nitrogen. Diameter (km) Average distance from Sun AU (1,426,725,400 km) Mass (kg) 5.69 x 1026 Rings are 270,000 km in diameter, but only a few hundred meters thick. Orbit eccentricity (deviation from circular) 0.056

Description Size Shape Color Special markings The origin of the rings of Saturn (and the other jovian planets) is unknown. They range in size from a centimeter or so to several meters »Two prominent rings (A and B) and one faint ring (C) can be seen from the Earth.

Planet Facts Surface conditions Climate Weather Temperature (highs/lows) atmosphere Saturn is the least dense of the planets; its specific gravity (0.7) is less than that of water. Like Jupiter, Saturn is about 75% hydrogen and 25% helium with traces of water, methane, ammonia and "rock", similar to the composition of the primordial Solar Nebula from which the solar system was formed. But this may not be sufficient to explain Saturn's luminosity; some additional mechanism may be at work, perhaps the "raining out" of helium deep in Saturn's interior.Solar Nebula

The name “Saturn” In Roman mythology, Saturn is the god of agriculture. The associated Greek god, Cronus, was the son of Uranus and Gaia and the father of Zeus (Jupiter). Saturn is the root of the English word "Saturday"mythology Cronus
