The ring is composed of several narrower rings, and bends, kinks and bright clumps in them can give the illusion that these strands are braided. There are actually many rings—maybe 500 to 1000. Saturn, ringed planet that is the second largest planet in the solar system in mass and size and the sixth nearest planet in distance to the Sun.

This flow rate was inferred to be 432–2870 kg/s using ground-based The densest parts of the Saturnian ring system are the A and B Rings, which are separated by the Cassini Division (discovered in 1675 by The D Ring is the innermost ring, and is very faint.

In the false-color IR view, greater water ice content and larger grain size leads to blue-green color, while greater non-ice content and smaller grain size yields a reddish hue. This ringlet exhibits irregular The A Ring is the outermost of the large, bright rings. Its inner boundary is the The thickness of the A Ring is estimated to be 10 to 30 m, its surface density from 35 to 40 g/cmSimilarly to the B Ring, the A Ring's outer edge is maintained by orbital resonances, albeit in this case a more complicated set. Huygens sent back amazing information and images from this strange world whose surface we have never seen.Cassini and Huygens made many exciting discoveries. NASA's Voyager mission visited the planet in the early 1980s. The ring particles mostly range from tiny, dust-sized icy grains to chunks as big as a house. But the rings are as little as 100 meters (330 feet) thick. Credit: NASAThe rings are about 400,000 kilometers (240,000 miles) wide.

They have been considered to possibly be very old, dating to the formation of Saturn itself. Using a 50× power refracting telescope that he designed himself, far superior to those available to Galileo, Huygens observed Saturn and in 1656, like Galileo, published the anagram "aaaaaaacccccdeeeeeghiiiiiiillllmmnnnnnnnnnooooppqrrstttttuuuuu". Saturn's satellite system is very lopsided: one moon, Titan, comprises more than 96% of the mass in orbit around the planet. The equator of the leading hemisphere of In October 2009, the discovery of a tenuous disk of material just interior to the orbit of Phoebe orbits the planet at a distance ranging from 180 to 250 radii. This series of photos was taken by the Hubble Space Telescope from 1996 through 2000. The structures shown (from 40 km wide ringlets at center to 300–500 km wide bands at right) remain sharply defined at scales below the resolution of the image.The B Ring's outer edge, viewed near equinox, where shadows are cast by vertical structures up to 2.5 km high, probably created by unseen embedded moonlets. They range from particles too tiny to see to "particles" the size of a bus.

The six other planemo (ellipsoidal) moons constitute roughly 4% of the mass, and the remaining 75 small moons, together with the rings, comprise only 0.04%. Saturn's rings are one of the most striking features of the solar system. Although reflection from the rings increases Saturn's The rings have numerous gaps where particle density drops sharply: two opened by known moons embedded within them, and many others at locations of known destabilizing Huygens was the first to suggest that Saturn was surrounded by a ring detached from the planet.
