There's a new king of rings in the solar system: An enormous new ring has been discovered around Saturn, made up of debris from the gas giant's distant moon Phoebe.
Before the discovery of this massive ring — about 12.5 times the average distance between the Earth and the moon in width and 6 times that distance in thickness — the largest known planetary rings were Jupiter's gossamer rings and Saturn's E ring.
