This Voyager 2 photograph of the outermost Uranian satellite, Oberon is a computer reconstruction of three frames , exposed through the narrow angle camera's blue, green, and orange filters. the grayness or apparent lack of strong color is a distinctive characteristic of the satellites and the rings of Uranus and can serve as one indicator of the possible composition of the satellites' surfaces. Oberon has a diameter of about 1,600 km. (1,000 mi.) and orbits the planet at a radial distance of 586,000 km. (364,000 mi.). Oberon's surface displays areas of lighter and darker material, probably associated in part with impact craters formed during its long exposure to bombardment by cosmic debris. Thr resolution of this particular image is not sufficient, however, to reveal with confidece the nature of these features.
