And then there's Prometheus, an awkward-looking creature that lives around Saturn's F ring. NASA's Cassini spacecraft got a lovely close-up view of Prometheus during a flyby on December 6.

Discovered in 1980, the small, elongated moon—it measures 136 kilometers along one axis, but only 79 and 59 along the other—orbits the planet just within Saturn’s outermost F ring.

The Cassini spacecraft team has digitally remastered this new image of Saturn's moon Prometheus, showing more clearly its oblong shape, as well as numerous craters over its 100-kilometer length.

Saturn gets close to the moon tonight, and skywatchers in Florida, northwestern South America, the Caribbean and Central America will see the ringed planet briefly disappear behind our lunar ...

The diminutive moon Prometheus whips gossamer ice particles out of Saturn’s F ring in this image taken by the Cassini spacecraft on Aug. 21, 2009.

The Cassini imaging scientists' findings show that Prometheus causes the structure as the moon approaches and recedes from the F ring every 14.7 hours, during its orbit of Saturn.

A pair of moons, Pandora and Prometheus, continue their shepherding duties near Saturn’s thin F ring. Pandora (81 kilometers, or 50 miles across) orbits outside the F ring and, with […] ...

Like the battered white whale Moby Dick taunting Captain Ahab, Saturn's moon Prometheus surges toward the viewer in a new 3-D image from NASA's Cassini spacecraft. The image exposes the irregular ...

Two naturalists explore the icy frontier on Saturn's inner moon Prometheus, as the ringed gas giant rises in the sky. These images of life in the outer ...

NASA's Cassini has captured another high-resolution image of Saturn's "potato moon" Prometheus at a distance of 23,000 miles. The spacecraft has previously taken high-res photos of the potato moon.
