Recent planetary physics and chemistry

Abstract

During the past few years considerable progress has been made in the knowledge and understanding of the origin of planets and of the structure of their interiors and atmospheres. Some of these advances, including Venera and Viking results, are reviewed for all the planets (except earth) with emphasis on those data that seem amenable to theoretical analysis. Results of the 1978-79 Mariner-Venus Orbiter, Pioneer 11, and Voyager 1 and 2 missions as well as other observations are briefly summarized.
