The F Ring is the outermost discrete ring of Saturn and perhaps the most active ring in the Solar System, with features changing on a timescale of hours. [133] It is located 3,000 km (2000 miles) beyond the outer edge of the A ring . [ 134 ]
Pan is the innermost named moon of Saturn. [4] It is approximately 35 kilometres across and 23 km wide and orbits within the Encke Gap in Saturn's A Ring.Pan is a ring shepherd and is responsible for keeping the Encke Gap free of ring particles.
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 has 146 known moons, 63 of which have formal names. [12] [11] It is estimated that there are another 100 ± 30 outer irregular moons larger than 3 km (2 mi) in diameter. [98] In addition, there is evidence of dozens to hundreds of moonlets with diameters of 40–500 meters in Saturn's rings, [99] which are not considered to be true moons.
See more on Saturn's rings: No telescope on this planet would ever have been able to see this. Cassini left Earth in 1997 and, in its nearly two decades of exploration, has sent home remarkable ...
A number of features in Saturn's rings are related to resonances with Mimas. Mimas is responsible for clearing the material from the Cassini Division, the gap between Saturn's two widest rings, the A Ring and B Ring. Particles in the Huygens Gap at the inner edge of the Cassini division are in a 2:1 orbital resonance with Mimas. They orbit ...
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.
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.
