<human>:  What is the difference between a meteor, an asteroid and a comet?
<bot>: The main difference between a meteor, an asteroid, and a comet is their composition and origin. A meteor is a small piece of rock or dust from outer space that enters the Earth's atmosphere and heats up due to friction, producing a bright streak of light or fireball. Meteors are usually composed of material from the asteroid belt. An asteroid is a larger chunk of rock or metal that is leftover material from the formation of the solar system and is located between Mars and Jupiter. Comets are composed of a mix of dust and frozen gases and typically originate from the outer solar system.
