A comet is a big ball of ice, dust and rock. The word ‘comet’ comes from the Greek word meaning ‘hair of the head’. It came from the Greek philosopher Aristotle who observed comets as ‘stars with hair’. Comets come from two major areas of our solar system: the Kuiper Belt and the Oort Cloud. Each of these regions contains billions of comets. A comet orbits the Sun. When close to the Sun, it displays a tail.
Where do Comets Come From?
