SOLAR SYSTEM

Detailed explanation-1: -The Kuiper Belt is a doughnut-shaped ring of icy objects around the Sun, extending just beyond the orbit of Neptune from about 30 to 55 AU.

Detailed explanation-2: -Definition. The Kuiper Belt is the region in the solar system beyond the orbit of Neptune that contains icy bodies orbiting the Sun.

Detailed explanation-3: -The Kuiper belt is a disk-shaped region of space beyond the orbit of Neptune that is dynamically stable. It is the source of short-period comets. The Oort cloud is much farther out than the Kuiper belt.

Detailed explanation-4: -The Oort Cloud is a predicted collection of icy objects farther away than everything else in the solar system. It fits with observations of comets in the planetary region of the solar system, but scientists have yet to observe any object in the Oort Cloud itself.

Detailed explanation-5: -There are likely billions of comets orbiting our Sun in the Kuiper Belt and even more distant Oort Cloud.
