The concept that Saturn's rings are made up of a series of tiny ringlets can be traced to Pierre-Simon Laplace, [4] although true gaps are few – it is more correct to think of the rings as an annular disk with concentric local maxima and minima in density and brightness. [2] On the scale of the clumps within the rings there is much empty space.
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.
The moonlet was first discovered in 2013, although its discovery was possible in 2012. [4] Cassini took 2 images of the edge of Saturn's A Ring, thereby ruling out it being a cosmic ray artifact. [3] There were disturbances at the edges of Saturn's A Ring, with one of these being approximately 20% brighter than its surroundings. There were also ...
The rings are named alphabetically in the order in which they were discovered. The main rings are A, B and C, with D, E and F being more recently discovered. There is also a very faint ring in the ...
Illustration by Elizabeth Brockway/The Daily BeastThe rings of Saturn are one of the most iconic structures in the solar system. Composed of billions of tiny chunks of ice and rock that are as ...
NASA's Cassini spacecraft sent back images looking over the shoulder of Saturn's rings. See more on Saturn's rings: No telescope on this planet would ever have been able to see this.
An artist's impression of Rhea's rings. The density of the particles is exaggerated greatly to aid visibility. [1] Rhea, the second-largest moon of Saturn, may have a tenuous ring system consisting of three narrow, relatively dense bands within a particulate disk. This would be the first discovery of rings around a moon.
In alchemy, each classical planet (Moon, Mercury, Venus, Sun, Mars, Jupiter, and Saturn) was associated with one of the seven metals known to the classical world (silver, mercury/quicksilver, copper, gold, iron, tin and lead respectively). As a result, the alchemical glyphs for the metal and associated planet coincide.
