Comet 87P/Bus is a periodic comet with an orbital period of 6.5 years. It fits the definition of an Encke-type comet with. It was discovered by Schelte J. Bus in 1981 on a plate taken with the 1.2m UK Schmidt telescope at Siding Spring, Australia. The discovery was announced in IAU Circular 3578 on March 4, 1981.
49P/Arend–Rigaux is a periodic comet in the Solar System.
60P/Tsuchinshan, also known as Tsuchinshan 2, is a periodic comet in the Solar System with an orbital period of 6.79 years. Tsuchinshan is the Wade-Giles transliteration corresponding to the pinyin Zĭjīn Shān, which is Mandarin Chinese for "Purple Mountain".
111P/Helin–Roman–Crockett is a periodic comet in the Solar System. It was discovered by Eleanor and Ron Helin on 5 January 1989 from images obtained on the 3rd and 4th of that month. It is a Jupiter family comet known for extremely close approaches to Jupiter being a Quasi-Hilda comet. During these approaches, it actually orbits Jupiter. The last such approach was in 1976, the next will be in 2071. The Jovian orbits are highly elliptical and subject to intense Solar perturbation at apojove which eventually pulls the comet out of Jovian orbit for the cycle to begin anew.
138P/Shoemaker–Levy, also known as Shoemaker–Levy 7, is a faint periodic comet in the Solar System. The comet last came to perihelion on 11 June 2012, but only brightened to about apparent magnitude 20.5.
152P/Helin–Lawrence is a periodic comet in the Solar System.
158P/Kowal–LINEAR is a periodic comet in the Solar System that has an orbit out by Jupiter.
165P/LINEAR is a periodic comet in the Solar System. 165P/LINEAR has a perihelion distance of 6.8 AU, and is a Chiron-type comet with.
170P/Christensen is a periodic comet in the Solar System. It came to perihelion in September 2014 at about apparent magnitude 18.
171P/Spahr is a periodic comet in the Solar System. 171P/Spahr was recovered on 20–24 October 2011 at apparent magnitude 20.6 using the 2.0-metre (79 in) Faulkes Telescope South. 171P/Spahr is peaked at about magnitude 18 in 2012.
11P/Tempel–Swift–LINEAR is a periodic Jupiter-family comet in the Solar System.
166P/NEAT is a periodic comet and centaur in the outer Solar System. It was discovered by the Near Earth Asteroid Tracking (NEAT) project in 2001 and initially classified a comet with provisional designation P/2001 T4 (NEAT), as it was apparent from the discovery observations that the body exhibited a cometary coma. It is one of few known bodies with centaur-like orbits that display a coma, along with 60558 Echeclus, 2060 Chiron, 165P/LINEAR and 167P/CINEOS. It is also one of the reddest centaurs.
178P/Hug–Bell is a periodic comet in the Solar System. It was discovered by Northeast Kansas Amateur Astronomers' League members Gary Hug and Graham Bell and is thought to be the first periodic comet to be discovered by amateurs. It was declared a comet less than two days after its initial discovery, after having its course confirmed on previous images.
Comet Taylor, is a periodic comet in the Solar System, first discovered by Clement J. Taylor on November 24, 1915.
144P/Kushida is a periodic comet discovered in January, 1994, by Yoshio Kushida at the Yatsugatake South Base Observatory in Japan. This was the first comet discovery of 1994 and his second discovery within a month. It next comes to perihelion on 25 January 2024 and should brighten to about magnitude 9.
94P/Russell 4 is a periodic comet in the Solar System. It fits the definition of an Encke-type comet with. It was discovered by Ken Rusell on photographic plates taken by M. Hawkins on March 7, 1984. In the discovery images, Russell estimated that the comet had an apparent magnitude of 13 and a noticeable tail of 5 arc minutes. In the year of discovery, the comet had come to perihelion in January 1984.
43P/Wolf–Harrington is a periodic comet discovered on December 22, 1924, by Max Wolf in Heidelberg, Germany. In 2019 it passed within 0.065 AU of Jupiter, which lifted the perihelion point and increased the orbital period to 9 years.
163P/NEAT is a periodic comet discovered on November 5, 2004 by Near-Earth Asteroid Tracking (NEAT) using the 1.2 meter Samuel Oschin telescope at Palomar Observatory.
62P/Tsuchinshan, also known as Tsuchinshan 1, is a periodic comet discovered on 1965 January 1 at Purple Mountain Observatory, Nanking. It will next come to perihelion on 25 December 2023 at around apparent magnitude 8, and will be 0.53 AU (79 million km) from Earth and 110 degrees from the Sun.
C/2012 K1 (PanSTARRS) is a retrograde Oort cloud comet discovered at magnitude 19.7, 8.7 AU from the Sun on 17 May 2012 using the Pan-STARRS telescope located near the summit of Haleakalā, on the island of Maui in Hawaii (U.S.).
