Answer 1

Answer:

Comets travel in orbits around the Sun. Some comets take less than 200 years to orbit the Sun. They are called short-period comets. Short-period comets are thought to originate in the Kuiper Belt, which is a belt of icy objects just beyond the orbit of the planet NEPTUNE. The dwarf planet PLUTO is located in this belt.  

Explanation:

Comets are composed of ice, dust and gas. Comets are categorized into two kinds: short period comets (P < 200 years) which come from Kuiper belt and long period comets (P >200 years) come from Oort clouds.

Kuiper belt resides beyond the orbit of the planet Jupiter. Kuiper belt contains many objects Comets, asteroids and dwarf planets. Pluto which is a dwarf planet is located in Kuiper belt.  Earlier it was considered as a planet but demoted to a dwarf planet in 2006.
