Rings and small satellites of Uranus

Rings and small satellites of Uranus

Fig. 11.9 . Eight of Uranusís small satellites circle the planet just outside its bright epsilon ring. This image, taken with the Hubble Space Telescope on 28 July 1997, is a false-color composite of three images taken at different infrared wavelengths in which Uranus appears relatively dim but the rings and moons do not. The satellites range in size from 40 kilometers across, for Bianca, to 150 kilometers for Puck. The arrows denote their direction of revolution about Uranus. White clouds are seen just above the planetís blue-green methane atmosphere. (Courtesy of NASA/STScI.)
