Enceladus (moon)
Enceladus[1] is a round, large moon of Saturn. It is the sixth largest Saturnian moon,[2][3][4] with a diameter of 500 km.[2] Enceladus is within Saturn's E ring.[2] It is made mostly out of water ice which reflects light very well.[5] It reflects almost 100% of the sunlight that strikes the moon.[6] Enceladus has been known by astronomers for a long time; it was discovered by William Herschel on August 28, 1789.[2] Scientists think that there may be an ocean under some of the icy surface. Scientists also think that there could be life in that ocean.
