The first reconnaissance of all the major planets of the Solar System culminated in the Voyager 2 encounter with Neptune in August 1989. Neptune itself was revealed as a planet with gigantic active storms in its atmosphere, and off-center magnetic field, and a system of tenuous, lumpy rings. Whereas only two satellites were known prior to the encounter, Voyager discovered six more. Triton, the largest satellite, was revealed as a frozen, icy world with clouds and layers of haze, and with vertical plumes of particles reaching five miles into the thin atmosphere. This latest Space Science Series volume presents the current level of understanding of Neptune, its riings, and its satellites, derived from the data received from the Voyager. The book's chapters are written by the world's leading authorities on various aspects of the Neptune system and are based on papers presented at an international conference held in January 1992. Covering details of Neptune's interior, atmosphere, rings, magnetic fields, and near-space environment--as well as the small satellites and the remarkable moon Triton--this volume is a unique resource for planetary scientists and astronomers requiring a comprehensive analysis of Neptune viewed in the context of our knowledge of the other giant planets. Until another spacecraft is sent to Neptune, Neptune and Triton will stand as the basic reference on the planet.
