Explanation: 

Detailed explanation-1: -Some exist in a wide disk beyond the orbit of Neptune called the Kuiper Belt. We call these short-period comets. They take less than 200 years to orbit the Sun. Other comets live in the Oort Cloud, the sphere-shaped, outer edge of the solar system that is about 50 times farther away from the Sun than the Kuiper Belt.

Detailed explanation-2: -The Oort Cloud is a spherical layer of icy objects surrounding our Sun, a star, and likely occupies space at a distance between about 2, 000 and 100, 000 astronomical units (AU) from the Sun.

Detailed explanation-3: -If you head in a direction in which there is no star nearby, after the edge of our Oort cloud you will likely find small rocks and other debris that is widely scattered and not bound to the gravity of a particular system.
