Scattered in orbits around the sun are bits and pieces of rock left over from the dawn of the solar system. Most of these objects, called planetoids or asteroids — meaning "star-like" — orbit between Mars and Jupiter in a grouping known as the Main Asteroid Belt.
Similarly one may ask, what is the asteroid belt and Kuiper Belt?
While many asteroids are composed primarily of rock and metal, most Kuiper belt objects are composed largely of frozen volatiles (termed "ices"), such as methane, ammonia and water. The Kuiper belt is home to three officially recognized dwarf planets: Pluto, Haumea and Makemake.
Where are the asteroid belt the Kuiper belt and the Oort cloud?
The Oort Cloud. The Kuiper Belt is a disk-shaped region past the orbit of Neptune extending roughly from 30 to 50 AU from the Sun containing many small icy bodies. It is now considered to be the source of the short-period comets.
How is the Oort cloud different from the Kuiper Belt?
Unlike the Kuiper Belt, the comets in the Oort Cloud circle the Sun in every direction. They do not stay on the flat disk. These objects break the rules of the Solar System and create a sphere of comets around the Sun.
