Washington, Jan 22 (PTI) NASA has released the closest view of Saturns wavemaker moon, Daphnis, captured as the Cassini spacecraft made one of its ring-grazing passes over the outer edges of the planets rings. Daphnis, measuring just eight kilometres across, orbits within the 42-kilometre wide area known as the Keeler Gap. The little moons gravity raises waves in the edges of the gap in both the horizontal and vertical directions. This is possibly due to the movement of fine ring particles being spread out into the gap following Daphnis last close approach to that edge on a previous orbit. A faint, narrow tendril of ring material is seen following just behind Daphnis.
