Diagram of the Phoebe ring The bulk of the ring material starts about six million kilometers (3.7 million miles) away from the planet and extends outward roughly another 12 million kilometers (7.4 million miles). The diameter of the ring is equivalent to 300 Saturns. The ring is also thick, about 20 Saturns across. It is tilted at about 27 degrees from the main ring plane and encompasses the orbit of the moon Phoebe. Both the ring and Phoebe orbit in the opposite direction of Saturn's other rings and most of its moons, including Titan and Iapetus. NASA / JPL-Caltech / SSI
