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.
The innermost D ring, and the C, B and A rings are easily seen. The F ring is also there, but not easily seen without enhancing the contrast of the image. (Rings were named in order of their discovery rather than their position around Saturn.) The rings also cast a shadow on Saturn at the limb of the planet in the lower right quadrant.
More close-up images of Saturn's moons were acquired, as well as evidence of changes in the atmosphere and the rings. During the flyby, the probe's turnable camera platform stuck for a couple of days and some planned imaging was lost. Saturn's gravity was used to direct the spacecraft's trajectory towards Uranus.

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.

The rings of Saturn are very close to its surface. They probably cover one-third of the sky when viewed from the Saturn's surface. About a half of the rings is in the shadow. So, I estimate the illuminance of the surface to be about 1/6 of the brightness of the rings.
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 ...
