What's the difference between a meteorite and a comet?
assistant
A meteor is a small piece of debris from an asteroid or comet that enters the Earth's atmosphere. It burns up as it passes through the atmosphere, creating a streak of light called a meteor. A comet is a large body made of dust and ice that orbits the Sun. When a comet gets close enough to the Sun, its ices can vaporize and create a visible atmosphere around the nucleus. The gases in the coma and tail are what make comets look like they have a fuzzy halo.
