ReneComets can be classified into two main types: short-period comets, which have orbits of less than 200 years and originate from the Kuiper Belt; and long-period comets, which have orbits of more than 200 years and originate from the Oort Cloud. Additionally, there are also sungrazing comets, which pass extremely close to the Sun.
