Saturn's Rings Created by Collision

SPACE.com -- Saturn's Rings Created by Collision

These small moonlets aren't big enough to sweep out all the dust on both sides of them, and form a gap in the rings of Saturn ... instead they manage to create two voids on either side of themselves .. one ahead of themselves and on the inward side .. and one further out in the ring system, and behind the moonlet's direction of rotation ... the gaps end up looking like S-shaped propellors, and the moonlet should be near the center of the "propellor".
