Explanation: Small, icy, inner moon of Saturn, Enceladus is only about 500
kilometers in diameter. But the distant world does reflect over 90
percent of the sunlight it receives, giving its surface about the same reflectivity
as fresh snow. Seen here in a sharp view from the Cassini
spacecraft's recent flyby, Enceladus shows a variety of surface
features and very few impact craters - indicating that it has been an active
world even |
