Tempel 1 is a periodic Jupiter-family comet discovered by Wilhelm Tempel in 1867. It completes an orbit of the Sun every 5.6 years. Tempel 1 was the target of the Deep Impact space mission, which photographed a deliberate high-speed impact upon the comet in 2005. It was re-visited by the Stardust spacecraft on February 14, 2011, and came back to perihelion in August 2016. On 26 May 2024, it will make a modest approach of 0.55 AU to Jupiter which will lift the perihelion distance and 9P will next come to perihelion on 12 February 2028 when it will be 1.77 AU from the Sun.
Comet Boethin was a periodic Jupiter-family comet discovered in 1975 by Leo Boethin. It appeared again in January 1986 as expected. Although the comet was next expected at perihelion in April 1997, no observations were reported, and the comet is thought to have disintegrated. It has not been observed since March 1986. The comet might have come to perihelion in late July 2020, but the uncertainty in the comet's position is hundreds of millions of km. The old orbit would have the comet next coming to perihelion around November 2031.
65P/Gunn is a periodic comet in the Solar System which has a current orbital period of 6.79 years. The comet is a short-period comet, orbiting the Sun every 6.79 years inside the main asteroid belt between the orbits of the planets Mars and Jupiter.
121P/Shoemaker–Holt, also known as Shoemaker-Holt 2, is a periodic comet in the Solar System with an orbital period of about 8 years. The comet was discovered by Carolyn S. Shoemaker, Eugene M. Shoemaker, and Henry E. Holt on 9 March 1989. The comet then had an apparent magnitude of 13, was diffuse and had a tail about 2 arcminutes long. It was recovered by James V. Scotti on 29 August 1995 in images obtained as part of the Spacewatch survey.
173P/Mueller, also known as Mueller 5, is a periodic comet in the Solar System with an orbital period of 13.6 years.
Comet Schaumasse is a periodic comet discovered by Alexandre Schaumasse on 1 December 1911 as 12th magnitude. It next comes to perihelion on 8 January 2026 and should brighten to about magnitude 9.
C/2007 F1 (LONEOS) is a hyperbolic comet discovered on March 19, 2007 as part as the Lowell Observatory Near Earth Object Search (LONEOS). The comet reached perihelion, or closest approach to the sun on October 28, 2007.
122P/de Vico is a periodic comet with an orbital period of 74 years. It fits the classical definition of a Halley-type comet with. It was discovered by Francesco de Vico in Rome on February 20, 1846.
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.
125P/Spacewatch is a periodic Jupiter-family comet. It was discovered on September 8, 1991, by Tom Gehrels using the 0.91 m Spacewatch telescope at the Kitt Peak National Observatory. It was the first comet discovered with the use of a CCD and also the faintest comet upon discovery up to that point. It has a diameter of 1.6 km.
Comet 252P/LINEAR is a periodic comet and near-Earth object discovered by the LINEAR survey on April 7, 2000. The comet is a Jupiter family comet, meaning that it passes quite close to the orbit of Jupiter.
104P/Kowal, also known as Kowal 2, is a periodic Jupiter-family comet discovered by Charles T. Kowal in 1979. The orbit was confirmed after new sightings in 1991 and 1998.
108P/Ciffréo is a periodic comet with an orbital period of 7 years discovered by Jacqueline Ciffréo on November 8, 1985. The comet is noted for having a peculiar double morphology, in which the nucleus is accompanied by a comoving, detached, diffuse tail, which is probably a perspective artifact of particles ejected sunwards and then repelled by solar wind.
126P/IRAS is a periodic comet with an orbital period of 13.4 years. It was discovered in images taken by the Infrared Astronomical Satellite (IRAS) on 28 July 1983 by J. Davies. The discovery was confirmed with images taken with the 1.2-m Schmidt telescope at Palomar Observatory.
Comet 141P/Machholz or 141P/Machholz 2 is a periodic Jupiter family comet with an orbital period of 5.3 years. It was discovered by Donald Machholz on 13 August 1994. A few days after the discovery a number of condensations were found near the main component of the comet, indicating that the comet had fragmented between 1987 and 1989, during its previous perihelion.
185P/Petriew is a periodic comet with an orbital period of 5.5 years. It was discovered by amateur astronomer Vance Avery Petriew on 18 August 2001.
207P/NEAT is a periodic Jupiter-family comet with an orbital period of 7.62 years. It was discovered by Near Earth Asteroid Tracking (NEAT) on 11 March 2001.
226P/Pigott–LINEAR–Kowalski is a Jupiter family periodic comet with an orbital period of 7.3 years. It was discovered by Edward Pigott on 19 November 1783, but was subsequently lost, until it was recovered on 5 January 2003 by Lincoln Near-Earth Asteroid Research (LINEAR). It will next come to perihelion on 27 December 2023 at about apparent magnitude 15.
249P/LINEAR is a periodic Jupiter-family comet with an orbital period of 4.61 years. It was discovered by LINEAR on 19 October 2006. It is only active for a brief period around perihelion.
323P/SOHO is a periodic comet with an orbital period of 4.15 years discovered in images obtained by the Solar and Heliospheric Observatory (SOHO). It is considered to be a sungrazing comet due to its perihelion being very close to the Sun. 323P/SOHO has the smallest perihelion of all numbered comets.
