Daphnis Makes Waves


daphnis-wavesDaphnis is one of Saturns small moons that is embedded in the Keeler gap in the ring system. This  image from Cassini shows it kicking up waves as it orbits.

Daphnis is only about 8 km across, but its gravity is powerful enough to disrupt the particles  near the edge of the A ring at the Keeler gap’s edge. Wave-like features form as the moon moves along.
