The diminutive size of cometary bodies is in no way proportional to their scientific importance. Theorists suggest that comets played a major role in the development of the Earth and subsequent collosions of comets may have wiped out various life forms, allowing only the most adaptable to develop further. In short, the study of comets is important from a historical perspective, scientifically compelling and, at the same time, entertaining. In this authoritative book, the development of cometary ideas is traced from antiquity through the actual fly-by of Halley by international spacecraft in 1986. The focus is on the cometary theories that were evident in each era. Included are many colorful anecdotes and information about culture and important personalities throughout history. Also contains an exhaustive catalog of all comet apparitions through the year 1700.

This volume describes Uranus, Neptune, Pluto and a host of comets which occupy our outer solar system. Illustrations depict the surfaces of these planetary bodies and the voyage of the "Pioneer" deep space probe.
