The Amazing Universe: Meteors and Comets

The video explains how Earth is constantly hit by meteoroids, which are small pieces of metal or stone from space. When these enter Earth's atmosphere, they burn up, creating meteors. Some meteoroids reach Earth's surface as meteorites, potentially causing craters. A significant meteorite impact is believed to have led to the extinction of dinosaurs. The video also covers comets, icy objects that orbit the Sun, forming a coma and tail as they near the Sun. Famous comets like Haley's and Hale-Bopp are discussed.
