Focusing on the remarkable achievements of Lewis Swift, this biography details his discovery of 13 comets and nearly 1,200 deep sky objects. Notably, all comets he identified are named after him, including three periodic comets with varying orbital periods of 6, 9, and 133 years. The book highlights Swift's significant contributions to astronomy and his lasting legacy in the field.
The book offers comprehensive research on more than 100 meteor streams, detailing their discovery, significant observations, and orbital paths. It presents an in-depth analysis of each meteor shower, including information on their duration and geographical location, providing readers with a complete understanding of these celestial events.
The sixth and final volume of Cometography provides complete details of every comet seen in the years between 1983 and 1993, featuring their brightnesses, physical descriptions, and orbits. This completes the definitive reference on comets for amateur and professional astronomers, and historians of science.
