When light passes into another material like glass or water, refraction causes it to bend. However, all the colors of light do not bend the same amount. At one end of the spectrum, red light bends the least, while at the other end, blue and violet light bend the most.
Twenty-four of Saturn's moons are regular satellites; they have prograde orbits not greatly inclined to Saturn's equatorial plane.
Saturn has, at present, 18 moons. They are Pan, Atlas, Prometheus, Pandora, Epimetheus, Janus, Mimas, Enceladus, Tethys, Telesto, Calypso, Dione, Helene, Rhea, Titan, Hyperion, Iapetus, and Phoebe. Contrary to popular belief, Uranus has the most moons, with 15 named and 6 being unnamed for a total of 21 moons.
