Uranus' mysterious moons: why NASA wants to explore Ariel and Miranda

Saturn’s rings are so much brighter than Jupiter's because they're made mostly of ice particles replenished by many small moons embedded in the rings. Jupiter’s dim, thin rings, by contrast, are made mostly of dust shed from a few small moons, and the large Galilean moons destroy any large rings.

Jupiter's rings may be so puny because of the planet's massive moons
