what do comets orbit around

Comets orbit around the Sun. They have elliptical orbits that bring them close to the Sun and then take them far away. There are two main types of comet orbits: short-period comets, which orbit the Sun in less than 200 years and generally originate from the Kuiper Belt beyond Neptune, and long-period comets, which have orbits lasting hundreds to millions of years and are thought to come from the distant Oort Cloud surrounding the solar system.
