This book presents a global and synthetic vision of planetology - the study of objects in the Solar System. In the past several decades, planetology has undergone a real revolution, marked in particular by the discovery of the Kuiper belt beyond Neptune, the discovery of extrasolar planets, and also by the space exploration of ever more distant objects. Today, it is at the crossroads of many disciplines: astronomy, geophysics, geochemistry and biology.

This book presents a global and synthetic vision of planetology - the study of objects in the Solar System. In the past several decades, planetology has undergone a real revolution, marked in particular by the discovery of the Kuiper belt beyond Neptune, the discovery of extrasolar planets, and also by the space exploration of ever more distant objects. Today, it is at the crossroads of many disciplines: astronomy, geophysics, geochemistry and biology. The Solar System 1 deals with the Solar System as a whole, offering a general presentation of the objects that compose it and its place in the galaxy. It also deals with planetary systems, exoplanets and the interaction of Solar System objects with interplanetary medium. Finally, it analyzes the telluric and giant planets.Hinweis: Dieser Artikel kann nur an eine deutsche Lieferadresse ausgeliefert werden.
