researchers remain working on a definite answer to these questions. in spite of where by they arrived from, they absolutely sure are stunning.
The ring particles are composed principally of h2o ice, and they range from grains the dimensions of sand up to house-sized boulders. An insider’s watch of the rings would possibly resemble a brilliant cloud of floating snowflakes and hailstones, using a couple of snowballs and bigger objects, most of them unfastened aggregates of smaller particles (Figure \(\PageIndex three \)).
towards the top of its mission, the Cassini spacecraft acquired nearer towards the rings of Saturn, but it really hardly ever received this near. (credit rating: modification of labor by NASA/JPL/University of Colorado).
in actual fact, it is best not to think of a ring rotating whatsoever, but instead to consider the revolution (or movement in orbit) of its particular person moonlets.

As well as the wide A, B, and C Rings, Saturn has a handful of extremely narrow rings no more than a hundred kilometers extensive.
, since their gravitation serves to “shepherd” the ring particles and continue to keep them confined to some narrow ribbon. A similar problem relates to the Epsilon Ring of Uranus, that is shepherded via the moons Cordelia and Ophelia.
