This completely rewritten new edition begins with an historical perspective of the place of the solar system in the universe. Evidence from meteorites is used to describe how the planets were formed and the giant planets are considered in the light of the discovery of new extrasolar giants. Other chapters discuss satellites, comets, centaurs, asteroids and why Pluto is not a planet. Explanations on why Earth and Venus turned out so differently, and how Mars and Mercury are the survivors of many similar bodies, are also discussed. The formation of the Moon in a giant impact leads to an assessment of the importance of collisions and impacts in the solar system. It is concluded that our solar system is the end product of many accidental and chance events. This leads to the philosophical discussion of whether planets like our Earth are likely to be found elsewhere in the universe.

This exciting tour of our Universe explores our current knowledge of exoplanets and the search for another Earth-like planet. Beginning with the basic concepts of planet formation and the composition of the Universe, Stuart Ross Taylor summarises our knowledge of exoplanets, how they compare with our planets and why some stars have better habitable zones. Further sections provide a detailed study of our Solar System, as a basis for understanding exoplanetary systems, and a detailed study of the Earth as our only current example of a habitable planet. The book concludes with a philosophical and historical discussion of topics surrounding planets and the development of life, including why our chances of finding aliens on exoplanets is very low. This is an engaging and informative read for anyone interested in planetary formation and the exploration of our Universe.
