That would be the "Oort Cloud" of comets.
Comets originate from the Oort cloud, a spherical shell of icy bodies at the outer edges of our solar system. These comets can be perturbed and sent into the inner solar system where they become visible as they approach the Sun.
The Oort cloud is thought to have formed from leftover material from the early solar system. Gravitational interactions with nearby stars and the giant planets may have scattered these icy bodies to the distant reaches of the solar system, forming the spherical Oort cloud.
It is estimated that there are trillions of comets in the Oort cloud. These comets are believed to be remnants from the early solar system and are located in a spherical region surrounding the solar system at distances ranging from about 2,000 to 100,000 astronomical units (AU) from the Sun.

The Oort Cloud
This is the Kuiper Belt. It is located just beyond Pluto. There is also the Oort Cloud that surrounds the whole solar system.

The Oort Cloud is believed to be a vast spherical region of icy debris extending far beyond the orbits of Neptune and Pluto. It is thought to be the source of long-period comets that occasionally enter the inner solar system.
This icy cloud is known as the Oort Cloud and is located about 1 to 3 light-years away from the Sun. It is believed to be the source of long-period comets that occasionally enter the inner solar system. The Oort Cloud is a remnant of the early solar system and holds valuable clues about its formation.
The Oort cloud is a hypothesized spherical cloud of icy objects that is thought to surround the Sun at distances of up to 1.6 light-years. It is located at roughly one-quarter of the way to Proxima Centauri, our nearest neighboring star. The Oort cloud is believed to be the source of long-period comets that occasionally enter the inner solar system.
