Made of rock and metal, they can also contain organic compounds. What is the difference An asteroid is a rocky object that orbits the Sun. Asteroids are small solar system bodies that orbit the Sun.However, if the meteoroid survives and lands on the surface of the Earth, or parts. When close enough to the Sun they display a visible coma (a fuzzy outline or atmosphere due to solar radiation) and sometimes a tail. Usually, the meteoroid is small enough that it gets burned up in the process.
