Comets are made of rock, dust, ice, and frozen gases. When comets approach the Sun, the frozen gases explosively sublime, forming the comet's coma (nebulous central mass) and scattering dust and ice into the solar wind. Lighter dust and photo-dissociated water molecules create the "tail" of the comet, which solar photons push outward in the direction away from the Sun.
Samples were retrieved from the comet 81P/Wild (Wild 2) by NASA's Stardust mission in 2006.
Comets are made up of rock, dust, water ice, carbon dioxide, ammonia, and methane. When a comet approaches the Sun, the heat causes these materials to vaporize and form a glowing coma and tail.

Frozen masses of gases and rocks?
in outer space we call them comets. on earth, we call them snowballs. Comets are thought to originate in Kuiper Belt and the Oort Cloud and consist of debris frozen together. Comets orbit in an elliptical pattern around the sun and produce the tail when near it. Snowballs, on the other hand, are usually formed only during the wintertime and tend to orbit in straight lines toward people's heads.

There are no comets on Neptune because Neptune is a planet and comets are, well, comets. They have nothing to do with each other.
