Comet Humason, formally designated C/1961 R1, was a non-periodic comet discovered by Milton L. Humason on September 1, 1961. Its perihelion was well beyond the orbit of Mars, at 2.133 AU. The outbound orbital period is about 2,516 years. The diameter of its comet nucleus is estimated at 30−41 km.
C/1652 Y1 was a naked-eye comet observed, among others, by Jan van Riebeeck. First spotted on December 14, 1652, in Mexico City, by Novohispano friar Diego Rodríguez, and next sighted on December 16, 1652, by Dutch observers at Pernambuco (Brazil).
The Eclipse Comet of 1948, formally known as C/1948 V1, was an especially bright comet discovered during a solar eclipse on November 1, 1948. Although there have been several comets that have been seen during solar eclipses, the Eclipse Comet of 1948 is perhaps the best-known; it was however, best viewed only from the Southern Hemisphere.
Miss Mitchell's Comet, formally designated as C/1847 T1, is a non-periodic comet that American astronomer Maria Mitchell discovered in 1847.
Comet Zhu–Balam, formally designated C/1997 L1, is a long-period comet first identified by David D. Balam on June 8, 1997, and originally photographed by Jin Zhu on June 3, 1997. The comet is estimated at 10 kilometres in diameter with a period of approximately 36,895 years.
Comet McNaught–Russell, formally designated as C/1993 Y1, is a long-period comet that reached a maximum magnitude of 6.5 in early 1994. It was discovered by Robert H. McNaught and Kenneth S. Russell using the U.K. Schmidt Telescope in Australia. McNaught and Russell worked at Siding Spring Observatory and together discovered five comets between 1991 and 1995.
C/1702 H1, also known as the "Comet of 1702", is a comet discovered by Maria Margaretha Kirch in Germany on April 20, 1702.
The JPL Small-Body Database (SBDB) is an astronomy database about small Solar System bodies. It is maintained by Jet Propulsion Laboratory (JPL) and NASA and provides data for all known asteroids and several comets, including orbital parameters and diagrams, physical diagrams, close approach details, radar astrometry, discovery circumstances, alternate designations and lists of publications related to the small body. The database is updated daily when new observations are available. In April 2021 the JPL Small-Body Database started using planetary ephemeris (DE441) and small-body perturber SB441-N16. Most objects such as asteroids get a two-body solution (Sun+object) recomputed twice a year. Comets generally have their two-body orbits computed at a time near the perihelion passage as to have the two-body orbit more reasonably accurate for both before and after perihelion. For most asteroids, the epoch used to define an orbit is updated twice a year. Orbital uncertainties in the JPL Small-Body Database are listed at the 1-sigma level.
Comet Beljawsky, formally designated as C/1911 S3, is a comet discovered by the Russian astronomer Sergei Ivanovich Beljawsky on September 29, 1911 and shortly thereafter, it was seen independently by four or five other observers in the United States and probably by others throughout the world. At the time it was discovered, the comet was near to the Sun which made observations difficult. However, several days after discovery it was a naked-eye object for a few days in the morning sky and later, after perihelion, as an evening object. It faded rapidly, becoming visible only in telescopes and was last seen on February 17, 1912. The comet sported a tail 8 to 10 degrees in length. In mid-October, the comet was visible in the evening sky together with another bright comet, C/1911 O1 (Brooks).
Comet Stonehouse, formally designated C/1998 H1, is a non-periodic comet discovered in April 22, 1998 by Patrick L. Stonehouse of Wolverine, Michigan, USA.
C/2013 UQ4 (Catalina) is a Solar System comet that came close to the Earth on July 10, 2014, at a distance of 0.314 AU (47,000,000 km; 29,200,000 mi).
C/1890 V1 (Zona) is a non-periodic comet discovered on November 15, 1890 by the Italian astronomer Temistocle Zona with an equatorially mounted Merz telescope at the Osservatorio Astronomico di Palermo. Whilst attempting to observe this comet, Rudolf F. Spitaler discovered the eponymous 113P/Spitaler in 1890.

P/2011 P1 (McNaught) was a Jupiter-family comet that passed extremely close to Jupiter on 4 December 2010 and disintegrated by 2012. It was discovered on 1 August 2011 by astronomer Robert H. McNaught at the Siding Spring Observatory in New South Wales, Australia. With an observation arc of 415 days, the comet's nominal orbit solution suggests that its 2010 approach distance was 0.00084 astronomical units from Jupiter's center—well within Jupiter's Roche limit at which the comet would be torn apart by tidal forces. The earliest precovery image of the comet was taken by Pan-STARRS 1 on 6 December 2010, two days after the comet's close pass with Jupiter.
C/1989 W1 (Aarseth–Brewington) is a non-periodic comet discovered on 16 November 1989 independently by Knut Aarseth and Howard Brewington. It reached an apparent magnitude of 2.8.
P/2003 T12 is a periodic comet that revolves around the Sun once every 4.11 years. On January 13, 2012, it was observed by the satellite STEREO-B, and the most documented phase of P/2003 T12 was observed on that date. It is theorized to be a possible fragment of comet 169P/NEAT.
C/2024 L5 (ATLAS) is a comet that was discovered on 14 June 2024 as A117uUD by the Asteroid Terrestrial-impact Last Alert System (ATLAS), South Africa, Sutherland. It will reach perihelion on 10 March 2025 at 3.432 AU (513.4 million km) from the Sun.
Comet Vozarova, formally designated C/1954 O1, is a hyperbolic comet discovered by Slovak astronomer, Margita Vozárová, on July 28, 1954.
