Enceladus, the sixth-largest moon of Saturn and about 500 kilometers in diameter, has the most reflective surface in the entire Solar System! Its bright, icy shell constantly gets refreshed by fine, icy particles from its own powerful geysers. These plumes blast out of the moon's south pole from a subsurface ocean—and they also supply the material for Saturn's beautiful E-Ring! ✨ #enceladus #saturn #moon #space #rings #IcyMoon #FactFriday | Beyond The Horizon
