	Saturn
		Saturn was first visited by NASA's Pioneer 11 in 1979 and later by Voyager 1 and Voyager 2.
		Saturn's interior is similar to Jupiter's consisting of a rocky core, a liquid metallic hydrogen layer and a molecular hydrogen layer.
		Saturn's outermost ring, the F-ring, is a complex structure made up of several smaller rings along which "knots" are visible.

	Saturn - Wikipedia, the free encyclopedia
		Saturn's interior is similar to Jupiter's, having a rocky core at the center, a liquid metallic hydrogen layer above that, and a molecular hydrogen layer above that.
		Saturn's usually-bland atmosphere occasionally exhibits long-lived ovals and other features common on Jupiter; in 1990 the Hubble Space Telescope observed an enormous white cloud near Saturn's equator which was not present during the Voyager encounters and in 1994 another, smaller storm was observed.
		Saturn appears to the naked eye in the night sky as a bright, yellowish star varying usually between magnitude +1 and 0 and takes approximately 29 and a half years to make a complete circuit of the ecliptic against the background constellations of the zodiac.

	Saturn
		Saturn is the sixth planet from the Sun and is the second largest in the solar system with an equatorial diameter of 119,300 kilometers (74,130 miles).
		Saturn's strong thermal glow at 5.1 microns even allows these deep clouds to be seen on portions of the dayside (left side), especially where overlying hazes are thin and the glint of the sun off of them is minimal.
		Saturn and two of its moons, Tethys (above) and Dione, were photographed by Voyager 1 on November 3, 1980, from a distance of 13 million kilometers (8 million miles).

		A paper published in Nature reports that the Cassini spacecraft has identified that moons Tethys and Dione are sources of plasma in Saturns magnetosphere.
		Soon after the Cassini spacecraft reached Saturn in June 2004, it revealed that the planets hurried rotation squashes the plasma into a disc and that great fingers of gas are being thrown out into space from the discs outer edges.
		Now, several years' worth of cosmic images of Saturn's 14 known small moons have been used to derive the sizes and shapes of most of them, and in about half the cases, even masses and densities.

		When Saturn passes in front of a star, it is possible to see the star's light shining through the rings.
		Voyager and Hubble observations of Saturn's rings led astronomers to think that the rings were relatively young and were perhaps the result of a moon ripped apart by tidal forces.

		The newly-found satellites were probably formed in the main asteroid belt between Mars and Jupiter, and scattered out of it by the tug of Jupiter's gravity.
		The new moonlet orbits approximately 136,505 kilometres from the centre of Saturn.
		The similarities of the Keeler gap features to those noted in Saturn's F ring and the Encke gap led imaging scientists to conclude that a small body, a few kilometres across, was lurking in the centre of the Keeler gap, awaiting discovery.

	Saturn’s Rings Surprise Cassini As the Spacecraft Flies By Titan - Planetary News \| The Planetary Society
		Earlier today, the spacecraft flew by Titan -- Saturn's largest moon and one of the primary targets of the mission -- and was expected to beam down raw images from that encounter at some point late today.
		Cassini's examination of Saturn's atmosphere began a couple of weeks ago as the spacecraft was still approaching the planet.
		"Saturn has a hydrogen atmosphere and we don't see oxygen there, so it has to come out of the solids of the system, the ice in the rings, somehow," Shemansky theorized.

		During its closest flyby of Saturn's moon Titan on April 16, the Cassini spacecraft came within 1,027 kilometers (638 miles) of the moon's surface and found that the outer layer of the thick, hazy atmosphere is brimming with complex hydrocarbons.
		Saturn’s hazy largest moon, Titan — a body long held to be a frozen analog of early Earth — has a surface shaped largely by an Earth-like interplay of tectonics, erosion by fluids, winds, and perhaps volcanism.
		Saturn's moon Titan is covered by "dirty" ice ridges and seas of liquid natural gas, a team of scientists said on Friday after a week of research into data from the space probe Huygens.

		If the satellite orbited 320 kilometers (200 miles) above the surface and its diameter was 0.3 meters (1 foot), with the same reflecting power as the Moon, it should be visible in a 7.6-centimeter (3-inch) telescope.
		Around 1950, when artificial satellites began to be discussed in earnest, everybody expected them to be just burned-out upper stages of multistage rockets, carrying no radio transmitters but being tracked by radar from the Earth.
		Their orbits are very close to each other, and the most interesting aspect of this satellite pair is that they regularly switch orbits with each other.

		The orbital speed of a body, generally a planet, a natural satellite, an artificial satellite, or a multiple star, is the speed at which it orbits around the barycenter of a system, usually around a more massive body.
		Inclination is one of the six orbital parameters describing the shape and orientation of a celestial orbit and is the angular distance of the orbital plane from the plane of the reference (usually planets equator or the ecliptic), stated in degrees.

		The dozens of moons orbiting Saturn vary drastically in shape, size, age and origin.
		In the case of Saturn's moons, these provisory names follow the format S/2005-S1, S/2005-S2 etc. Once the existence of the moon is confirmed and its orbit determined, the moon is given a final name by the International Astronomical Union, the organization that since 1919 assumed this task.
		In the case of Saturn, moons are named after Saturn's brothers, the Titans, and Saturn's sisters, the Titanesses.

		Using a telescope that was far superior to those available to Galileo, Huygens observed Saturn and wrote that "It [Saturn] is surrounded by a thin, flat, ring, nowhere touching, inclined to the ecliptic." [http://www2.jpl.nasa.gov/saturn/back.html]
		On March 10, 2006, NASA reported that the Cassini probe found evidence of liquid water reservoirs that erupt in geysers on Saturn's moon Enceladus [http://saturn.jpl.nasa.gov/news/press-release-details.cfm?newsID=639].

		The fact that most of the satellites' orbits are retrograde and eccentric speaks volumes about their origins: They had to have come from elsewhere, and been captured by the planets at some point.
		In the case of the irregular satellites, they could not have shifted from an orbit around the Sun to an orbit around one of the giant planets without slowing down -- through friction in an atmosphere, perhaps; the influence of gravity; or a collision with another object...
		Retrograde satellites lose momentum to the parent body and slowly spiral inward, which puts an upper limit on the length of time the retrograde moons have spent as satellites, and obviously, will spend as satellites.
