what is saturn's composition and appearance
Saturn, the sixth planet from the sun, is one of four âgas giants.â It is easily recognized by its set of rings. The rings were originally discovered by Galileo in 1610, although he did not know what he was looking at and instead described Saturn ashaving âears.â Saturnâsrings are made mostly ofice and rock.
