A comet is composed of dust, rock particles, and frozen gases. It typically features a nucleus at its core, surrounded by a glowing coma—a cloud of gas and dust. When a comet approaches the Sun, solar radiation causes the gases to sublimate, forming a tail that always points away from the Sun due to solar wind.

What state of matter is comets?

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.
