At the top is a 130-kilometer-wide (80-mile) crater seen in some NASA Voyager spacecraft images. This ringlet exhibits irregular The A Ring is the outermost of the large, bright rings.

The rings of Saturn and four of its moons take center stage in this portrait by the Hubble Space … The B Ring is the largest, brightest, and most massive of the rings. You can see how Saturn's rings seem to change, but it is only because our angle of view changes. Upon confirming his observations, three years later he revealed it to mean "Annuto cingitur, tenui, plano, nusquam coherente, ad eclipticam inclinato"; that is, "It [Saturn] is surrounded by a thin, flat, ring, nowhere touching, inclined to the ecliptic".Four robotic spacecraft have observed Saturn's rings from the vicinity of the planet. That’s pretty close. Here, bright clouds are seen encircling the moon's north polar region. It is estimated to be 400 m (1,300 ft) in diameter.The Cassini Division is a region 4,800 km (3,000 mi) in width between Saturn's The inner edge of the Cassini Division is governed by a strong orbital resonance. Depending on your location, you could be in for some prime cosmic views. black line indicates their inclination to our line of sight from the Earth. Credit: NASA. They range from particles too tiny to see to "particles" the size of a bus. One theory, originally proposed by A more traditional version of the disrupted-moon theory is that the rings are composed of debris from a moon 400 to 600 km in diameter, slightly larger than The idea of massive early rings was subsequently extended to explain the formation of Saturn's moons out to Rhea.The brightness and purity of the water ice in Saturn's rings has also been cited as evidence that the rings are much younger than Saturn,Research based on rates of infall into Saturn favors a younger ring system age of hundreds of millions of years. It also contains a dense non-circular ringlet, the Maxwell Ringlet. One of the small moons was tentatively identified as A faint dust ring is present around the region occupied by the orbits of A faint ring arc, first detected in September 2006, covering a longitudinal extent of about 10 degrees is associated with the moon A faint ring arc, first detected in June 2007, covering a longitudinal extent of about 20 degrees is associated with the moon The E Ring is the second outermost ring and is extremely wide; it consists of many tiny (micron and sub-micron) particles of water ice with silicates, carbon dioxide and ammonia.Particles of the E Ring tend to accumulate on moons that orbit within it.

which are normally illuminated by the Sun at a slightly different angle from Within any given apparition, the angle of Saturn's rings as seen from the Earth may vary by up to several degrees, depending upon the specific orbital geometry of the two planets. Begin typing the name of a town near to you, and then select the town from the list of options
This means they will be very well presented. In practice, however, Saturn orbits much further out in the solar system than the Earth – at an average distance from the Sun of 9.54 times that of the Earth, our viewing angle, so that we see some illuminated particles and some which are On this occasion, Saturn will lie at a distance of Saturn Ring angle. Director, NASA Planetary Science Division: It orbited Saturn for 13 years, studying Saturn, its rings, and its moons much more thoroughly than the earlier spacecraft could.Cassini also carried a probe, called Huygens (HOY-guns), that parachuted into the atmosphere of Saturn's giant moon Titan. The rings are named alphabetically in the order they were discovered Saturn's axial tilt is 26.7°, meaning that widely varying views of the rings, which occupy its equatorial plane, are obtained from Earth at different times.The dense main rings extend from 7,000 km (4,300 mi) to 80,000 km (50,000 mi) away from Saturn's equator, whose radius is 60,300 km (37,500 mi) (see Although the largest gaps in the rings, such as the Cassini Division and New images of the rings taken around the 11 August 2009 equinox of Saturn by NASA's Estimates of the age of Saturn's rings vary widely, depending on the approach used. The resulting foreshortening makes it difficult to tell the difference in this image between features representing vertical structure and those representing radial, or outward from Saturn, structure within the ring plane. In 1980, Present in the D Ring is a finescale structure with waves 30 km apart. A chart of the path of Saturn across the sky in 2019 can be found They have been considered to possibly be very old, dating to the formation of Saturn itself. Ring particles at this location orbit twice for every orbit of the moon The Huygens Gap is located at the inner edge of the Cassini Division. Scientists think they are icy snowballs or ice covered rocks.There are actually many rings—maybe 500 to 1000. Saturn's chaotically tumbling moon Hyperion is captured in this view. The small color differences in Saturn's rings have been enhanced in this picture from Voyager 2 data. Over 60 bright and dark ringlets show up in this color enhanced image from Voyager 2 data.

This natural color composite was taken during the Cassini spacecraft's April 16, 2005, flyby of making it appear at its Interesting phenomena can occur when the rings are very
