That is a totally NO!
There are no comets on Neptune because Neptune is a planet and comets are, well, comets. They have nothing to do with each other.
No. Comets come from beyond the asteroid belt, mostly from a region called the Kuiper Belt, beyond the orbit of Neptune.
yes
Beyond the orbit of Neptune
Comets are typically found in the outer regions of the solar system, beyond the orbit of Neptune. They can be observed from Earth when they come closer to the sun and develop a visible tail due to the solar wind. Astronomers track comets using telescopes and space missions.
-- Despite where they come from, some comets have different mass qualities. While some are long-term comets, some are short-term. Short-term period comets originate in the Kuiper belt or it's "shattered disc", which is around the orbit of Neptune. Long-term period comets originate in Oort cloud, which is a cloud of icy bodies in space.
Comets in the solar system originate from two main sources: the Kuiper Belt beyond Neptune and the Oort Cloud much further out. These icy bodies are remnants from the early solar system and are occasionally pulled in by gravitational forces into orbits that bring them closer to the Sun, resulting in their characteristic tails.
The vast disk of icy comets near Neptune's orbit is called the Kuiper Belt. It is a region of the outer Solar System that contains numerous small icy bodies and serves as a source of short-period comets.
Short period comets that originate beyond the orbit of Neptune but are generally moving level with the orbits of the other planets are in the Kuiper Belt. The Kuiper Belt is a region of the outer solar system that contains icy bodies, including comets, that orbit the Sun beyond Neptune.
Comets are relatively small chunks of rock and ice that orbit the sun, sometimes they come close but usually are far out beyond the orbit of Neptune. Stars are different, they are like our sun. Much bigger and hotter but much further away.
They come from the outer reaches of space.
