Phoebe

(fee -bee) A small satellite of Saturn, discovered in 1898 by William Henry Pickering. It is the largest of Saturn's outer satellites, roughly spherical in shape with a diameter of 220 km. It follows a retrograde orbit, circling the planet once every 548.2 days at a mean distance of nearly 13 million km. Voyager 2 photographed Phoebe after passing Saturn in 1981, revealing a surface that is dark, with an albedo of 0.06, Phoebe is red in color but not as red as Iapetus. Its rotation period is about 9.4 hours, so Phoebe may not be in synchronous rotation with Saturn.

Phoebe was imaged again by the Cassini probe in June 2004 just before the spacecraft entered orbit around Saturn. The images Cassini returned, taken from a distance of 2078 km, revealed a tiny world heavily scarred by impact craters. Many of the impacts had excavated material from within the satellite's crust, hurling enormous rocks out onto its surface. The images also revealed alternating light and dark material around some of the craters. Other sensors aboard Cassini found that Phoebe contains not only water ice but also carbon dioxide. The geological and chemical complexities of Phoebe lead scientists to believe that it is not a captured asteroid, as was first thought, but an icy planetesimal, similar in makeup to a Kuiper Belt object, that was captured about 4000 million years ago by the spinning gas disk that eventually became Saturn.

Phoebe

 

a satellite of the planet Saturn. Phoebe’s diameter is 300 km, and its mean distance from the center of the planet is 12,950,000 km. Phoebe was discovered in 1898 by W. Pickering. It revolves around Saturn in the direction opposite to the planet’s rotation about its axis.

(astronomy)
A satellite of the planet Saturn; its diameter is judged to be about 190 miles (320 kilometers); it has an eccentric orbit and retrograde revolution.
