This volume identifies the similarities and differences in the processes of formation and evolution of all planets in the solar system. By comparing common processes and features of the planets, including Earth, we are better able to understand Earth as a planet, and the evolutionary processes that have led to its present state. As a result of these studies, we will acquire a better understanding of other planets, such as Venus and Mars. The results can then be iterated to achieve a common consensus. The prediction of future evolution is a definite ultimate goal. Also recommended as a reference source for graduate students in the planetary sciences who are interested in comparative studies of the planets.
