Phoebe rotates through nearly one full rotation in this animated sequence of nine color frames, taken on Cassini's approach to the small moon on June 10, 2004. Phoebe rotates on its axis once every 9 hours and 16 minutes; this sequence spans 8 hours and 14 minutes; all 360 degrees of longitude on Phoebe are visible in this sequence.
The surface is clearly covered by impact craters of a wide range of sizes, up to 40% the diameter of the moon, creating rugged topography illustrated dramatically along the terminator and limb.
The images that make up this sequence were obtained at a phase, or Sun-Phoebe-spacecraft, angle of 87 degrees, and from distances ranging from 877,453 kilometers (545,341 miles) to 688,924,000 kilometers (428,169 miles). The image scale ranges from 5.3 to 4.1 kilometers (3.3 to 2.6 miles) per pixel. To aid visibility, the images were magnified three times via linear interpolation; no contrast enhancement was performed.
The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the Cassini-Huygens mission for NASA's Office of Space Science, Washington, D.C. The imaging team consists of scientists from the US, England, France, and Germany. The imaging operations center and team lead (Dr. C. Porco) are based at the Space Science Institute in Boulder, Colo.
