Comet Characteristics and Behavior

The video tutorial provides an in-depth look at comets, explaining their nature, composition, and structure. It clarifies that comets are not stars but celestial objects with distinct characteristics, such as a nucleus, coma, and tails. The tutorial also covers the origins of the term 'comet', their elliptical orbits around the sun, and the materials they are composed of, including dust and frozen gases. Additionally, it discusses the formation of comet tails due to solar radiation and classifies comets based on their orbital paths into long-tailed and short-tailed comets.
