D Ring
The D Ring is the innermost ring of Saturn. It located inward of the C Ring, and is very faint indeed.
C Ring
The C Ring is one of the rings of Saturn, locating inward from the B Ring. It is wide, but fainter than the A Ring and B Ring, and seems to be composed of darker material. It is thus sometimes referred to as the Crepe Ring.
Columbo Gap
Maxwell Gap
B Ring
The B Ring is one of the rings of Saturn. It is the innermost of the two largest, brightest rings. Unlike the A Ring, it is made of innumerable ringlets, some of which have eccentric orbits. There are also spoke-like features running across it, which are made of suspended dust particles.
Cassini Division
The Cassini Division is a 4,800 km (2,980 mile) gap between Saturn's A Ring and B Ring. It was discovered in 1675 by Giovanni Cassini.From Earth it appears as a thin black gap in the rings, but during the Voyager pass, it was discovered that the gap was full of tiny rings.
All of the gaps in Saturn's rings are caused by the gravitational pull of one or more of Saturn's moons affecting the orbits of the tiny particles of which the rings are comprised. Saturn's moon Mimas is responsible for clearing the material from the Cassini Division.
Huygens Gap
A Ring
The A ring is one of the rings of Saturn. It is the outermost of the two largest, brightest rings. Its inner boundary is the Cassini Division and its sharp outer boundary is the orbit of the small moon Atlas. The A Ring is divided in two near its outer edge by the Encke Division which is caused by the presence of the small moon Pan. A smaller, fainter division is called the Keeler Gap, and is kept clear by the moonlet Daphnis.
Encke Division
The Encke Division, also called the Encke Gap, is a perceived gap within Saturn's A Ring.
The division starts at a distance 133,580 kilometers from Saturn's center extending another 325 kilometers. Within this gap, Saturn's moon Pan orbits.
Images from the Cassini probe have shown that there is a thin, knotted ringlet within the gap.
Keeler Gap
The Keeler Gap is a 42-kilometre-wide gap in Saturn's A Ring, approximately 250 kilometres from the ring's outer edge. It is named after the astronomer James Edward Keeler. The small moon Daphnis, discovered May 1 2005, orbits within it, keeping it clear.
R/2004 S 1
R/2004 S 1, also known as S/2004 1R, is the temporary designation of a newly discovered ring around the planet Saturn. It lies between the A Ring and the F Ring, in the orbit of the moon Atlas. The faint, thin ring was discovered by the Cassini probe imaging team and announced on September 9, 2004.
R/2004 S 2
R/2004 S 2 is a temporary designation for a recently discovered faint ring of Saturn. It was discovered by the Cassini probe imaging team and was announced in 2005. The ring is located at 138,900 km from Saturn's center, between the orbits of Atlas and Prometheus.
F Ring
The F Ring is one of the outer rings of Saturn. It is located outside the larger rings, just beyond the A Ring. It is very thin, and is held together by two shepherd moons, Prometheus and Pandora, which orbit inside and outside it.
Recent images from the Cassini probe show that the F Ring consists of one core ring and a spiral strand around it when seen in closeup [1]. They also show that Prometheus's gravitational attraction creates kinks and knots in the F Ring as the moon 'steals' material from it.
G Ring
The G Ring is one of the rings of Saturn. It is a very thin, faint ring about halfway between the F Ring and the beginning of the E Ring.
E Ring
- For other meanings see E Ring (disambiguation).
The E Ring is one of the rings of Saturn. It is the outermost ring, and is extremely wide, beginning at the orbit of Mimas and ends somewhere around the orbit of Rhea. It is a diffuse disk of icy or dusty material. Unlike the other rings, it is composed of microscopic rather than macroscopic particles. In 2005, the moon Enceladus was determined to be the source of E Ring's material.
