"Comets are celestial objects, comprised of frozen gases, rock, and dust, that orbit the sun. When a comet hurtles near the sun, its dusts and gases heat up and form a halo and a tail. In this informational book, readers learn the scientific history of discovering and identifying comets, the difference between comets and other space objects, and more. Photographs and artist renderings of comets and their paths help readers understand these amazing astronomical phenomena"-- Provided by publisher
