Cometa

Comets have a solid core composed of rock, dust, ice, and frozen gases like carbon dioxide, carbon monoxide, and ammonia. They are believed to originate in the cold, dark regions of the solar system. Comets become visible when their orbits bring them closer to the sun, causing the frozen gases to evaporate.
