Paperback. Zustand: New. Print on Demand. This book presents the results of spectroscopic and polariscopic observations conducted in 1871 on Encke's Comet. The author provides detailed notes and remarks on the comet's search, discovery, and appearance after discovery, including four drawings made from sketches on different dates…. These drawings illustrate the changes in form the comet underwent as it approached and receded from the sun. The author also examines the comet's physical characteristics, such as its mass, density, and composition. Through this examination, the author concludes that the comet was composed mainly of carbon in a gaseous state and that its mass was approximately equal to that of an asteroid. The book contributes significantly to our understanding of Encke's Comet and provides insights into the nature and behavior of comets in general. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.
