This textbook emphasizes key basic principles of planetary science
that help to unify the study of the solar system. It is organized in a hierarchical manner so that every chapter builds upon preceding ones.
Starting with historical perspectives on space exploration and the development of the scientific method, the book leads the reader through the solar system. The presentations concerning the planets and their satellites emphasize that their origin and subsequent evolution can be explained by applications of certain basic principles of physics, chemistry, and celestial mechanics and that the surface features of the solid bodies in the solar system can be interpreted by means of the principles of geology.
