The region outside of Pluto is known as "The Kuiper Belt
The region is called the Kuiper Belt. It is a disk-shaped region lying beyond the orbit of Neptune that is home to numerous icy bodies, including dwarf planets such as Pluto.
The Kuiper belt is thought to contain matter that was left over from the formation of the solar system
There are various small bodies in the solar system .These include moon, asteroids, rocks etc.
Small icy bodies are located in the solar system where they orbit the sun.

The eight planets of our system are not considered small solar system bodies, to qualify as a planet in the first place means that they have to be quite large. Small solar system bodies are such things as comets, asteroids, meterorids, moons or minor planets.
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.
The luminosity of a quasar is generated in a region roughly the size of our solar system. This incredibly small region, known as an accretion disk, contains a supermassive black hole at its center that feeds on surrounding material, releasing a tremendous amount of energy in the process.
