Enceladus is a round, large moon of Saturn. It is the sixth largest Saturnian moon, with a diameter of 500 km. Enceladus is within Saturn's E ring. It is made mostly out of water ice which reflects light very well. It reflects almost 100% of the sunlight that strikes the moon. Enceladus has been known by astronomers for a long time; it was discovered by William Herschel on August 28, 1789. 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.
