The Solar System
The nucleus of a comet is mostly solid, while the coma and tail of the comet is composed of gasses and (we believe) a lot of dust. As the comet approaches the Sun, sunlight heats the nucleus of the comet and melts some of the frozen gasses, which sublimate into space carrying dust into space, forming the coma and the tail of the comet.
