Detailed explanation-1: -The Kuiper Belt is a source of comets, as it very slowly erodes itself away. Pieces produced by colliding KBOs can be pushed by Neptune’s gravity into orbits that send them sunward, where Jupiter’s gravity further corrals them into short loops lasting 20 years or less.
Detailed explanation-2: -The Kuiper Belt is one of the largest structures in our solar system – others being the Oort Cloud, the heliosphere, and the magnetosphere of Jupiter. Its overall shape is like a puffed-up disk or donut. Its inner edge begins at the orbit of Neptune, at about 30 AU from the Sun.
Detailed explanation-3: -The short-period comets are thought to originate in the Kuiper Belt, an area outside Neptune’s orbit (from about 30 to 50 AU) that has many icy comet-like objects. The long-period comets tend to have orbits that are randomly oriented, and not necessarily anywhere near the ecliptic.
