SOLAR SYSTEM

Detailed explanation-1: -The Oort Cloud lies far beyond Pluto and the most distant edges of the Kuiper Belt. While the planets of our solar system orbit in a flat plane, the Oort Cloud is believed to be a giant spherical shell surrounding the Sun, planets and Kuiper Belt Objects.

Detailed explanation-2: -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.

Detailed explanation-3: -(But the Oort Cloud extends even farther) The Kuiper Belt shouldn’t be confused with the Oort Cloud, which is an even more distant, spherical region of icy, comet-like bodies that surrounds the solar system, including the Kuiper Belt.

Detailed explanation-4: -Both the Oort Cloud and the Kuiper Belt are thought to be sources of comets.

Detailed explanation-5: -The coma is a cloud of gases that surrounds the nucleus of a comet. In some comets, a cloud of hydrogen gas surrounds the coma.
