<human>:  Is there a difference between a meteor and a comet?
<bot>: Yes, there is a difference between a meteor and a comet. A meteor is a small piece of rock or dust from space that enters the Earth's atmosphere, resulting in a bright flash of light in the night sky as it heats up and disintegrates. A comet is typically larger and is made of ice, dust, and rocky material which releases gases when it comes close to the Sun's heat. These gases form a visible aura around the comet, called a coma, which can be seen with the naked eye.
