This book surveys the current state of knowledge of the solar system and recommends a suite of planetary science flagship missions for the decade 2013-2022 that could provide a steady stream of important new discoveries about the solar system.
The Solar System comprises the Sun and its planetary system, as well as a number of dwarf planets, satellites, and other objects that orbit the Sun. It formed 4.6 billion years ago from the gravitational collapse of a giant molecular cloud.
