Paperback. Condition: New. Print on Demand. This book is a compilation of three treatises on the nature, origins, and significance of comets, penned by Johannes Kepler in the early 17th century. Kepler offers a detailed and scientific examination of these celestial phenomena, challenging the prevalent Aristotelian view of comets as atmospheric disturbances and instead positing that they originate in the vast expanse of the cosmos beyond Earth's atmosphere. Through meticulous observation and analysis of data, Kepler proposes that comets traverse the celestial sphere along elliptical paths, often extending far beyond the orbit of Saturn. He further speculates on their physical composition, suggesting they are composed of a tenuous, ethereal substance that condenses and becomes visible as they approach the Sun. Kepler's work on comets, grounded in empirical evidence and pioneering a new understanding of their nature, laid the groundwork for subsequent astronomical investigations and contributed significantly to the development of modern astronomy.
