Long-period comets are comets that take more than 200 years to complete an orbit around the Sun. Unlike short-period comets, which generally originate from the Kuiper Belt, long-period comets are believed to originate from the Oort Cloud, a distant and spherical shell of icy bodies that surrounds the solar system.
