28P/Neujmin, also known as Neujmin 1, is a large periodic comet in the Solar System. With a perihelion distance of 1.5AU, this comet does not make close approaches to the Earth.
41P/Tuttle–Giacobini–Kresák is a periodic comet in the Solar System. The comet nucleus is estimated to be 1.4 kilometers in diameter.
42P/Neujmin, also known as Neujmin 3, is a periodic comet 2 km in diameter.
48P/Johnson is a periodic comet in the Solar System.
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 Zǐjīn Shān 紫金山, which is Mandarin Chinese for "Purple Mountain".
77P/Longmore is a periodic comet in the Solar System, with a period of 6.8 years.
128P/Shoemaker–Holt, also known as Shoemaker-Holt 1, is a periodic comet in the Solar System. The comet passed close to Jupiter in 1982 and was discovered in 1987. The comet was last observed in March 2018.
157P/Tritton is a periodic comet with a 6-year orbital period. Fragment B was first observed on 21 August 2022.
7P/Pons–Winnecke is a periodic Jupiter-family comet with a six-year orbit. Early calculations for the 1921 apparition suggested that the orbit of the comet might collide with Earth in June, but observations on 10 April ruled out an impact. It made a very close approach to Earth in June 1927. The outward migration of perihelion created impressive meteor showers in 1916, 1921 and 1927.
11P/Tempel–Swift–LINEAR is a periodic Jupiter-family comet in the Solar System.
18D/Perrine–Mrkos is a periodic comet in the Solar System, originally discovered by the American-Argentine astronomer Charles Dillon Perrine on December 9, 1896. For some time it was thought to be a fragment of Biela's Comet.
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 Crommelin, also known as Comet Pons-Coggia-Winnecke-Forbes, is a periodic comet with an orbital period of almost 28 years. It fits the classical definition of a Halley-type comet with. It is named after the British astronomer Andrew C. D. Crommelin who calculated its orbit in 1930. It is one of only four comets not named after their discoverer(s), the other three being Comets Halley, Encke, and Lexell. It next comes to perihelion around May 27, 2039 when it will be near a maximum near-perihelion distance from Earth.
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.
C/2000 W1 (Utsunomiya–Jones) is a long-period comet from the Oort cloud discovered on November 18, 2000, by Syogo Utsunomiya and Albert F. A. L. Jones. The comet reached up to apparent magnitude 5.5, but was only 27 degrees from the Sun in mid-December 2000.
62P/Tsuchinshan, also known as Tsuchinshan 1, is a periodic comet first discovered January 1, 1965 at the Purple Mountain Observatory in Nanking. It last came to perihelion on 25 December 2023 at around apparent magnitude 8, and was then 0.53 AU (79 million km) from Earth and 110 degrees from the Sun.
246P/NEAT is a periodic comet discovered on 2004 March 28 by Near-Earth Asteroid Tracking (NEAT) using the 1.2-metre (47 in) reflector at Haleakala. It was given the permanent number 246P on 2011 January 14.
