I can be described as a dirty snowball because I’m made mostly of frozen water and dust. Some scientists believe that comets are responsible for bringing some water and organic mol ecules to Earth’s surface at the beginning of the Solar System. My most distinctive characteristic is my coma sweeping out behind me as I travel through space. This tail is a result of passing close to the Sun, evaporating my ice into water and releasing dust. We comets orbit the Sun, but in elongated orbits, not circular ones, sending me far out into space, but always to return back again. Show more
