SOLAR SYSTEM

Detailed explanation-1: -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.

Detailed explanation-2: -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. It is a spherical region surrounding the Sun out to near 50, 000 AU.

Detailed explanation-3: -The short-period comets (such as Halley) are thought to originate in the Kuiper belt, where small gravitational perturbations from Neptune can gradually shift their orbits until they can penetrate the inner solar system.

Detailed explanation-4: -Meteoroids are even found on the edge of the solar system, in regions called the Kuiper belt and the Oort cloud. Different meteoroids travel around the sun at different speeds and in different orbits. The fastest meteoroids travel through the solar system at a speed of around 42 kilometers (26 miles) per second.
