Saturn's Ring System
The rings of Saturn have puzzled astronomers ever since they were discovered by Galileo in 1610, during the first telescopic observations of the night sky. The puzzles have only increased since Voyagers 1 and 2 imaged the ring system extensively in 1980 and 1981.
Saturn, the ringed planet
Saturn, the large gas giant beyond Jupiter and sixth planet from the Sun, is one of the five (Mercury, Venus, Mars and Jupiter) planets visible from Earth using only the naked-eye.
SATURN THE RINGED PLANET
Way out beyond Jupiter is the second of the gas giants, Saturn.
When Galileo focused his telescope on Saturn he was puzzled to find that it had an irregular shape.
By Brian Ventrudo
More than a few stargazers got their start with a first look at Saturn through a telescope. The planet is simply a beautiful object.
Saturn eclipses an icy moon
The mighty planet Saturn is circled by a fleet of moons, each as different from the other as individual people. And as weird and alien as it seems, this Saturnian system of planet and moons have some similarities to our own Earth and Moon.
Saturn as seen by Hubble ©NASA and The Hubble Heritage Team (STScI/AURA) Saturn is probably the best known and most beautiful planet in the solar system.
Here is a planet that everyone knows something about. Nearly anyone who has spent some time in school can recognize its because of its rings, but what else do you know about the Saturnian world? Do you know for instance what those famous rings are made of?
Saturn's New Moons
Many new Saturnian moons are now confirmed; the pre-2000 reports are probably in error. More recent discoveries can be seen here. And more discoveries are expected from Cassini, now in orbit around Saturn.
Saturns Smaller Moons
Last week, we looked at the largest gem in Saturns vast collection satellite treasures, Titan. This week, we will look at other, smaller in the Saturnian system.
Saturn has many moons (62 discovered as of 2012). The moons are: Titan, Rhea, Iapetus, Dione, Tethys, Enceladus, Mimas, Hyperion; Prometheus, Pandora (shepherd moons), Phoebe, Janus, Epimetheus, Helene, Telesto, Calypso, Atlas, Pan, Ymir, Paaliaq, Siarnaq, Tarvos, Kiviuq, Ijiraq, ...

Saturn is the _______________________ planet from the Sun in our Solar System. It is the second-largest _______________________ in our Solar System (Jupiter is the largest) and is made mostly of _______________________ and helium gas (it is a _______________________ planet).
A highly oblate whose atmosphere is hydrogen and helium. The predominant condensable aerosols are methane, ammonia, hydrogen sulfide, and water. In order of decreasing condensation height (as well as saturation vapor pressure), the condensable gases are CH4, NH3, NH4SH NH3H2S, and H2O.
Saturn has 31 known moons. Of them, Titan is the largest, and is the second-largest in our solar system (Jupiter's Ganymede is largest). The other satellites have icy surfaces and many craters. Mimas has one crater that spans one quarter of it's diameter.
Saturn was the god of agriculture, he was called Cronus by the Greeks. He is the son of Uranus, and father of Jupiter. Saturn over threw his father to become king of the gods, but was then over thrown himself by his son Jupiter.
Saturn transits - or passes in front of - the Crab Nebula on the evening of January 4. Afterwards, Saturn slowly drifts westward (left to right) through Taurus, staying within vicinity of the Crab Nebula throughout the month.
Saturn advertises itself as "a different kind of car company" although it is actually a division of General Motors. Saturn prides itself on dealerships that feature the "Saturn Difference," which means, among other things, no-haggle pricing.
Saturn has 34 named moons, among them Titan, about the size of Jupiter's Ganymede, both larger than the planet Mercury.
Saturn's renowned rings appear to be mostly made of small particles of water ice, some of which may be coating rocky particles.

Saturn is the sixth planet from the Sun and the second largest planet in the Solar System, after Jupiter.
Saturn's other Moons
Saturn's other moons have icy surfaces that are very cold so that ice is as rigid as rock and craters form from meteor impacts. The mean densities of these moons are 1.0 to 1.5 g/cc, implying that they are probably mostly ice, though they may have some rocky consituents.

Venus and Saturn will pair up in the western sky on the evening of June 30th.
The planets will pass 41' apart around 9 P.M. EDT (01:00 UT, July 1st).

Saturn has intrigued man for centuries, especially since the invention of the telescope when the Saturn's grand rings were observed for the first time. Much like Jupiter, Saturn has many dozens of moons, one of which, Enceladus, could provide a foot-hold for life to form.

Saturn is the sixth planet and the second jovian giant. Saturn is 120,000 km (75,000 miles) across and about 95 times Earth's mass, one day lasts 10 hours 15 minutes. The atmospheres composition is 94 percent Hydrogen, and the rest is helium with traces of ammonia, methane,and other gases.
Such spots are relatively rare on Saturn. The previous one visible from Earth appeared in 1933, but it was much smaller than the 1990 system and much shorter lived, lasting for only a few weeks. Another storm system is visible in Figure 12.2, taken in 1994.

Saturn, the farthest planet easily visible to the unaided eye, is known for its extensive, complex system of rings, which are very impressive even in a small telescope. Using a small telescope one can also discern the planet's oblateness, or flattening at the poles.
The rings of Saturn are made up of icy particles ranging in size from micrometres to metres. Almost entirely water ice, the particles are contaminated with some dust and other chemicals.

The Saturn Nebula was discovered by Sir William Herschel in the late 18th century. It got its name from the English astronomer and telescope maker William Parsons, 3rd Earl of Rosse, in the 19th century.

Saturn's largest satellite is the mysterious world called Titan. It has slightly greater diameter, density, and mass than Callisto. It is probably half rock, half ice. What is special about Titan is that it has a thick atmosphere with a surface air pressure about 1.5 times thicker than the Earth's.
Saturn with its fantastic rings is about 1 light hour from the Sun. These are "false color" image from Voyager. Saturn's large satellite Titan is massive enough to have its own atmosphere, though probably too cold to support life.
The sixth planet in the solar system, noted for its obvious ring structure. Saturn is almost ten times the Earth's distance from the Sun. The planet completes a circuit around the Sun in about 30 Earth years. Saturn is the second largest and the least dense planet in our solar system.

For example, Saturn has a specify gravity, or density, of 0.71. Therefore an equal volume of water would weigh more than the planet - if you had a big enough bowl of water, Saturn would float in it! On the other hand, Earth has a specific gravity of 5.5, thus Earth would weigh 5.
