Like planets, comets revolve around the sun. However, they are different from asteroids because of their composition. Asteroids are usually made of rocky and mineral materials.
Comets look like a huge snowball, made of ice, dust, and some rocky material. You can recognize them in the night sky by their long tails, which can stretch for millions of kilometers.
