This is Daphnis, one of Saturn's moons. This image shows its unusual gravitational effect on Saturn's rings ...
Daphnis is only about 8 km wide, but its gravity disturbs Saturn's A ring, creating ripples and edge waves. It orbits within the Keeler Gap, a 42 km-wide gap in the rings. This image shows how even small moons can shape massive ring systems
