... 2010 February 17 . An Unusually Smooth Surface on Saturn's Calypso . ... Explanation: Why is this moon of Saturn so smooth? ... Like its sister moon Telesto and the shepherd moon Pandor a , Calypso has shown itself to be unusually smooth, much smoother than most of Saturn's larger moons. A leading hypothesis for Calypso 's smoothness is that much of the moon's surface is actually a relatively loose jumble of rubble -- making Calypso a rubble-pile moon. ... About APOD | ...
