This close pairing of Janus and Epimetheus shows the two moons at “high phase,” meaning that only a thin sliver of sunlit terrain is visible on each moon. Portions of each are also lit feebly by ...

A new diffuse ring, coincident with the orbits of Saturn's moons Janus and Epimetheus, has been revealed in ultra-high phase angle views from Cassini. The new ring is visible in this image (marked by ...

Outside the soft edge of Cassini’s F ring, Epimetheus and Janus negotiate their nearly-shared orbit. The two moons’ orbits are typically about 50 kilometers (30 miles) apart, and the moons actually ...

On this day in 1966, Richard Walker discovered one of Saturn’s inner moons, called Epimetheus… sort of. Walkers observation of a moon on December 18th came three days after an observation of a similar ...

Saturn's 62 moons range from overgrown rocks that are less than a half-mile wide to giant Titan, which is bigger than the planet Mercury. These pictures from the Cassini orbiter show off two "quartets ...

An image of Saturn's small moon, Epimetheus (epp-ee-MEE-thee-uss), was captured by the Cassini spacecraft in the closest view ever taken of the pockmarked body. Epimetheus is irregularly shaped and ...
