Physics of the Solar System is based on the earlier work by B. Bertotti and P. Farinella: Physics of the Earth and the Solar System (Kluwer, 1990), which has been completely revised and updated, and more focused on the solar system. It generally attains a higher level than the previous version. This volume is generally suitable for post-graduate students and researchers in physics, especially in the field related to the solar system. A large amount of figures and diagrams is included, often compiled with real data.
