At the perihelion passage on 2 August 2026 the solar elongation is calculated at 164 degrees, with apparent magnitude approximately 8, with closest approach to Earth on 3 August 2026 at a distance of 0.414 AU (61.9 million km).
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.
36P/Whipple is a periodic comet in the Solar System. It is the lowest numbered Quasi-Hilda comet. It passed 0.25 AU (37 million km) from Jupiter in June 1922.
42P/Neujmin, also known as Neujmin 3, is a periodic comet 2 km in diameter.
47P/Ashbrook–Jackson is a periodic comet in the Solar System.
49P/Arend–Rigaux is a periodic comet in the Solar System.
84P/Giclas is a periodic comet in the Solar System. The comet nucleus is estimated to be 1.8 kilometers in diameter. In 1995 precovery images from three nights in September 1931 by Clyde W. Tombaugh were located.
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.
143P/Kowal–Mrkos is a periodic comet in the Solar System.
118P/Shoemaker–Levy is a comet discovered by astronomers Carolyn and Eugene M. Shoemaker and David Levy.
Comet Finlay is a periodic comet with an orbital period of 6 years discovered by William Henry Finlay on September 26, 1886. The next perihelion passage is July 13, 2021 when the comet will have a solar elongation of 54 degrees at approximately apparent magnitude 10. It last came to perihelion on December 27, 2014, at around magnitude 10. Of the numbered periodic comets, the orbit of 15P/Finlay has one of the smallest minimum orbit intersection distances with the orbit of Earth (E-MOID). In October 2060 the comet will pass about 5 million km from Earth.
118401 LINEAR (provisional designation 1999 RE70, comet designation 176P/LINEAR) is an active asteroid and main-belt comet that was discovered by the Lincoln Near-Earth Asteroid Research (LINEAR) 1-metre telescopes in Socorro, New Mexico on September 7, 1999. (118401) LINEAR was discovered to be cometary on November 26, 2005, by Henry H. Hsieh and David C. Jewitt as part of the Hawaii Trails project using the Gemini North 8-m telescope on Mauna Kea and was confirmed by the University of Hawaii's 2.2-m (88-in) telescope on December 24–27, 2005, and Gemini on December 29, 2005. Observations using the Spitzer Space Telescope have resulted in an estimate of 4.0±0.4 km for the diameter of (118401) LINEAR.
23P/Brorsen–Metcalf is a periodic comet with an orbital period of 70 years. It fits the classical definition of a Halley-type comet with. It was first discovered by Theodor Brorsen at the Altona Observatory on July 20, 1847, and again by Kaspar Schweizer (Moscow) on August 11, 1847. It was predicted that it would reappear between 1919 and 1922.
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.
82P/Gehrels is a periodic comet that was discovered on October 27, 1975, by Tom Gehrels at the Palomar Mountain Observatory in California having a faint nuclear brightness of magnitude 17.
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.
51P/Harrington is a periodic comet in the Solar System.
