Saturn Moon May Have Rings Too
Saturn’s second-largest moon Rhea could be a mini version of its ringed parent, and the first moon known to have rings of its own. Scientists detected the rings from an electron measurement when the Cassini spacecraft flew by Rhea in November 2005.
So far, Cassini has not been able to actually see the rings. If the spacecraft’s mission is extended, researchers hope it might be able to photograph the rings on a future flyby of Rhea.
Rhea, named after the classical-Greek Titan goddess and mother of Zeus, is a barren, icy world covered in craters. Its diameter is a little less than half that of our moon.
