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.
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.
Larger rocks and boulders may also be present, and in 2007 tidal effects from eight moonlets only a few hundred meters across were detected within Saturn's rings. The maximum size of a ring particle is determined by the specific strength of the material it is made of, its density, and the tidal force at its altitude. The tidal force is ...
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.
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 ...
A study published in the journal Science suggests a hypothetical moon (called Chrysalis) came too close to Saturn's gravitational pull and was torn apart, forming the planet's iconic rings.
Enceladus orbiting within Saturn's E ring. Plumes from Enceladus, which are similar in composition to comets, [25] have been shown to be the source of the material in Saturn's E ring. [23] The E ring is the widest and outermost ring of Saturn (except for the tenuous Phoebe ring).
If you love looking at the stunning rings of Saturn, here's a heads-up: They're going to vanish from our view briefly.
