Three Little Moons

Another lovely study of Saturn's rings and little moons:

Three of the small worlds that hug the outer edges of Saturn's immense ring system are captured in this Cassini spacecraft portrait (Select the image for a closer look, or the link for the Cassini-Huygens home page).

The two F ring shepherd moons, Prometheus (102 kilometers, or 63 miles across) and Pandora (84 kilometers, or 52 miles across) are seen flanking the ring at bottom. Janus (181 kilometers, or 113 miles across) is visible near the top of the scene.
