32P/Comas Solà is a periodic comet with a current orbital period of 8.8 years.
101P/Chernykh is a periodic comet which was first discovered on August 19, 1977, by Nikolaj Stepanovich Chernykh. It will next come to perihelion in 2034.
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.
164P/Christensen is a periodic comet in the Solar System.
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.
45P/Honda–Mrkos–Pajdušáková is a short-period comet discovered by Minoru Honda December 3, 1948. It is named after Minoru Honda, Antonín Mrkos, and Ľudmila Pajdušáková. The object revolves around the Sun on an elliptical orbit with a period of 5.25 years. The nucleus is 1.3 kilometers in diameter. On August 19 and 20, 2011, it became the fifteenth comet detected by ground radar telescope.
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.
P/2011 NO1 (Elenin) is a periodic comet with a preliminary orbital period estimated at 13 ± 0.16 years. It came to perihelion (closest approach to the Sun) around 20 January 2011 at 1.2 AU from the Sun. The orbit is preliminary as it has only been observed over an observation-arc of 22 days. The comet was discovered on 7 July 2011 when the comet was 2.38 AU from the Sun and 1.4 AU from the Earth. It came to opposition 178.6° from the Sun on 22 July 2011 in the constellation Sagittarius.
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.
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.
209P/LINEAR is a periodic comet with an orbital period of 5.1 years. The comet has extremely low activity for its size and is probably in the process of evolving into an extinct comet.
276P/Vorobjov is a Jupiter-family comet discovered on 15 October 2012 by Tomáš Vorobjov on three 120-s images taken remotely using the 0.81-m f/7 Ritchey-Chretien Schulman Telescope located at the Mt. Lemmon SkyCenter via the Sierra Stars Observatory Network in the course of a minor-planet search survey undertaken as part of the International Astronomical Search Collaboration (IASC) school campaigns. After posting on the Minor Planet Center's NEOCP webpage, other observers have commented on the object's cometary appearance. The discovery was announced by the Minor Planet Center on 18 October, three days after the discovery.
75D/Kohoutek is a short-period comet discovered in February 1975, by Luboš Kohoutek. Even on the discovery plate the comet was only apparent magnitude 14. Assuming the comet has not disintegrated the 2020-2021 perihelion passage is only expected to peak around apparent magnitude 20.
C/2013 R1 (Lovejoy) is a long-period comet discovered on 7 September 2013 by Terry Lovejoy using a 0.2-meter (8 in) Schmidt–Cassegrain telescope. It is the fourth comet discovered by Terry Lovejoy. C/2013 R1 crossed the celestial equator on 14 October 2013, becoming a better Northern Hemisphere object.
266P/Christensen is a periodic comet in the Solar System. It will next come to perihelion in December 2026. It has been suggested as the source of the 1977 "Wow! Signal".
335P/Gibbs is a periodic comet in the Solar System. It last came to perihelion in August 2022. Together with 266P/Christensen, it was proposed as the source of the 1977 "Wow! Signal".
