Scientists refer to the study of comets and other celestial bodies as astronomy or astrophysics, depending on the specific focus of the research. Cometary science involves studying the composition, behavior, and origins of comets, while broader astronomical research includes investigating the entire universe, including stars, planets, and galaxies.

comets are formed from ice and gases
A comet is an icy body that releases gas or dust. They are often compared to dirty snowballs, though recent research has led some scientists to call them snowy dirtballs. Comets contain dust, ice, carbon dioxide, ammonia, methane and more. Astronomers think comets are leftovers from the gas, dust, ice and rocks that initially formed the solar system about 4.6 billion years ago. Some researchers think comets might have originally brought some of the water and organic molecules to Earth that now make up life here. To research this hypothesis, the Rosetta mission, which landed a probe on a comet on Nov. 12, 2014, is studying its nucleus and environment, observing how it changes as it approaches the sun. Comets orbit the sun, but most are believed to inhabit in an area known as the Oort Cloud, far beyond the orbit of Pluto. Occasionally a comet streaks through the inner solar system; some do so regularly, some only once every few centuries. Many people have never seen a comet, but those who have won't easily forget the celestial show.

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