Cometa

The video explores the nature and history of comets, which were once seen as omens. Comets are icy bodies from the solar system's outskirts, composed of a nucleus, coma, and tail. They differ from asteroids and meteors in structure and location. Comets are categorized by their orbital periods into short-period and long-period comets. Halley's Comet, a well-known short-period comet, is expected to return in 2061. The video concludes with a reflection on the future of comets and their appearances.
