Fact Sheet
Peek-A-Boo Moon
Helene, a small moon of Saturn, peeks into view at the corner of this recent image from the Cassini spacecraft, with Saturn itself in the background. Helene is a small chunk of rock and ice. It has been battered by smaller moons, making it look like a knobby root vegetable. This is one of the sharpest images of Helene to date, and reveals details as small as a few hundred yards in diameter. Cassini flew past the moon on March 3. [NASA/JPL/SSI]
