NASA's Cassini spacecraft captured Saturn's moon Prometheus, orbiting near the streamer-channels it has created in the thin F ring, casts a shadow on the A ring in this image taken a little more than a week after the planet's August 2009 equinox.
Saturn's small moon Prometheus, slightly overexposed in this image taken by NASA's Cassini spacecraft, shows off its potato-like shape as it orbits in the Roche Division between the A ring and thin F ring.
Saturn's potato-shaped moon Prometheus is rendered in three dimensions in this close-up from NASA's Cassini spacecraft. You will need 3-D glasses to view this image.
Saturn's small, potato-shaped moon Prometheus appears embedded within the planet's rings near the center of this view from NASA's Cassini spacecraft while the larger moon Mimas orbits beyond the rings.
Saturn's moon Prometheus casts a narrow shadow on the rings near the much larger shadow cast by the planet in this image taken by NASA's Cassini spacecraft about five months after Saturn's August 2009 equinox.
The effects of the small moon Prometheus loom large on two of Saturn's rings in this image taken by NASA's Cassini spacecraft a short time before Saturn's August 2009 equinox.
NASA's Cassini spacecraft captured this close view of Saturn's moon Pandora during the spacecraft's flyby on June 3, 2010. Pandora orbits beyond Saturn's thin F ring.
Appearing like eyes on a potato, craters cover the dimly lit surface of the moon Prometheus in this high-resolution image from NASA's Cassini spacecraft's early 2010 flyby.
The gravity of potato-shaped Prometheus periodically creates streamer-channels in the F ring, and the moon's handiwork can be seen in the dark channels in this image from NASA's Cassini spacecraft.
Saturn's moon Prometheus casts a long shadow across the A ring in the middle-right side of this image taken shortly before the planet's August 2009 equinox by NASA's Cassini spacecraft.
