Prometheus and Pandora and the F ring

Prometheus and Pandora and the F ring
Prometheus and Pandora and the F ring Prometheus (left) and Pandora (right) are small, elongated moons that orbit inside and outside the F ring, respectively. Cassini was slightly less than half a million kilometers from Pandora when it took this photo of the pair on 29 October 2005. Prometheus is 148 by 68 kilometers in size, and Pandora is 110 by 62 kilometers. Note the small streamer of material that Prometheus has drawn out of the inner edge of the F ring during a recent collision. NASA / JPL-Caltech / SSI / Emily Lakdawalla
