Paperback. Condition: New. Print on Demand. This book takes readers into the realm of comets and dives into the heart of groundbreaking theories on their movement and nature. Moving past antiquated beliefs that viewed comets as mere atmospheric clusters, the author builds upon the advancements of Tycho Brahe and Johannes Kepler to propose that comets are celestial bodies subject to physical laws. They assert that comets follow fixed parabolic paths and orbit the Sun like the planets, tracing out predictable trajectories in the cosmos. This paradigm-shifting perspective laid the foundation for the field of cometary science.
