• Sommario/riassunto: This book contains the proceedings from a workshop on planetary sciences sponsored by the Academy of Sciences of the USSR and the National Academy of Sciences. The proceedings include papers written by American and Soviet scientists who examine the current theoretical understanding of how the planets were formed and how they evolved to their present state. They assess the type of observations and experiments that are needed to advance understanding of the formation and evolution of the solar system based on the current theoretical framework.
