Asteroids are generally considered to be made up of metals and rocky material, while comets are made up of ice, dust and rocky material. ... Asteroids formed much closer to the sun, where it was too warm for ices to remain solid.

there are small chunks of rock and debris in the space.they become meteors for when they fall through Earth's atmosphere leaving a bright tail whereas comets are small bodies with the head and a long luminous tail and they appear after a long period of time i.e. 76yrs
