The book begins with a historical review of four major theories for
the origin of the Solar System in particular, or of planets in
general, which highlight the major problems that need to be solved
by any plausible theory. In many theories, including that which
form the major theme of this book, the formation of planets and
stars is intimately linked, so four chapters are devoted to the
processes that can be described as the birth, life and death of
stars. Recent observations that have revealed the existence of
planets around many Sun-like stars are described in detail,
followed by a clear exposition of the Capture Theory for the origin
of planets. Many aspects of this theory are illustrated with
sophisticated computer modelling that convincingly demonstrates the
plausibility of the theory. The Capture Theory is in complete
accord with all observations, including the estimate it gives for
the proportion of Sun-like stars with planets. It is the only
theory that sits comfortably with all present observational and
theoretical constraints. The general theory of planet formation
does not explain the detailed structure of the Solar System. An
early postulated collision of two major planets is shown to explain
many disparate features of the Solar System - the nature of the
terrestrial planets, surface features of the Moon and its
relationship with Earth, asteroids, comets and dwarf planets, the
relationship between Neptune, Triton and Pluto and the
characteristics of meteorites, including the isotopic anomalies
found in them. The postulate of a planetary collision is given
support by a 2009 NASA observation of the residue of such an event
around a distant young star.
