Comet

The video explores the nature of comets, which were historically seen as omens. Comets are small celestial bodies made of dust, gases, and ice, originating from the solar system's outer regions. They consist of a nucleus, coma, and tail, and are distinct from asteroids and meteors. Comets are categorized into short-period and long-period types based on their orbital duration. Halley's Comet, a well-known short-period comet, is discussed, including its historical sightings and future return. The video concludes with reflective questions about the viewer's future when Halley's Comet returns.
