The latter include the D Ring, extending inward to Saturn's cloud tops, the G and E Rings and others beyond the main ring system. These diffuse rings are characterised as "dusty" because of the small size of their particles (often about a μm); their chemical composition is, like the main rings, almost entirely water ice. The narrow F Ring ...
Saturn has the most spectacular ring system, with seven rings and several gaps and divisions between them. Few missions have visited Saturn: Pioneer 11 and Voyagers 1 and 2 flew by, but Cassini ...
Saturn’s rings are seen as viewed by NASA’s Cassini spacecraft, which obtained the images that comprise this mosaic at a distance of approximately 450,000 miles from Saturn April 25, 2007.
NASA released up-close images of Saturn's rings. NASA's Cassini spacecraft sent back images looking over the shoulder of Saturn's rings. See more on Saturn's rings:

A ring system is a disc or torus orbiting an astronomical object that is composed of solid material such as dust, meteoroids, planetoids, moonlets, or stellar objects. Ring systems are best known as planetary rings, common components of satellite systems around giant planets such as the rings of Saturn, or circumplanetary disks.
In an image captured by the Hubble Space Telescope, Saturn’s rings display an unexplained phenomenon that looks like spokes moving across its rings.
S/2009 S 1 is a moonlet embedded in the outer part of Saturn's B Ring, orbiting 117,000 km (73,000 mi) away from the planet.The moonlet was discovered by the Cassini Imaging Team during the Saturnian equinox event on 26 July 2009, when the Cassini spacecraft imaged the moonlet casting a 36 km (22 mi)-long shadow onto the B Ring.
