Five moons and a ring (annotated)
Five moons and a ring (annotated) On 17 September 2011 at about 1200 UTC, Cassini pointed at the mid-sized moon Dione and watched as it transited Titan while the rings and two small moons passed by. Pan is a tiny object orbiting within the A ring's Encke gap, while Pandora is the outer shepherd satellite of the F ring. NASA / JPL-Caltech / SSI / animation by Emily Lakdawalla
