Chacornac's Comet, formally designated as C/1852 K1, is a faint parabolic comet that was observed through telescopes between May and June 1852. It is the only comet discovered by French astronomer, Jean Chacornac, and is the parent body of the Eta Eridanids meteor shower. [5] [a]
Jean Chacornac made his only comet discovery from the Marseille Observatory on 16 May 1852, where he spotted a "faint, diffuse object" without a discernible tail nor nucleus on the constellation Cepheus. [b] He later confirmed his discovery the following day. [4]
Jean Chacornac was a French astronomer and discoverer of a comet and several asteroids.
3200 Phaethon, provisionally designated 1983 TB, is an active Apollo asteroid with an orbit that brings it closer to the Sun than any other named asteroid. For this reason, it was named after the Greek Hero, Phaëthon, son of the sun god Helios. It is 5.8 km (3.6 mi) in diameter and is the parent body of the Geminids meteor shower of mid-December. With an observation arc of 35+ years, it has a very well determined orbit. The 2017 Earth approach distance of about 10 million km was known with an accuracy of ±700 m.
20 Massalia is a stony asteroid and the parent body of the Massalia family located in the inner region of the asteroid belt, approximately 145 kilometers in diameter. Discovered by Italian astronomer Annibale de Gasparis on 19 September 1852, it was named for the Latin name of the French city of Marseille, from which the independent discover Jean Chacornac sighted it the following night. It was the first asteroid that was not assigned an iconic symbol by its discoverer.
25 Phocaea is a stony asteroid from the inner regions of the asteroid belt, approximately 75 kilometers in diameter. It is the parent body of the Phocaea family. Discovered by Jean Chacornac in 1853, it was named after the ancient Greek city of Phocaea.
Comet IRAS–Araki–Alcock is a long-period comet that, in 1983, made the closest known approach to Earth of any comet in the last 200 years, at a distance of about 0.0312 AU.
13P/Olbers is a periodic comet with an orbital period of 69 years. It fits the classical definition of a Halley-type comet with a period between 20 and 200 years. The comet last passed perihelion 30 June 2024 and it was previously seen in 1956. The next perihelion is in 2094.
Comet C/1861 G1 (Thatcher) is a long-period comet with roughly a 422-year orbit that is expected to return around 2283. It was discovered by A. E. Thatcher. It is responsible for the April Lyrid meteor shower. Carl Wilhelm Baeker also independently found this comet. The comet passed about 0.335 AU from the Earth on 5 May 1861 and last came to perihelion on 3 June 1861.
1622 Chacornac is a stony Flora asteroid from the inner regions of the asteroid belt, approximately 9 kilometers in diameter. It was discovered on 15 March 1952, by French astronomer Alfred Schmitt at the Royal Observatory of Belgium in Uccle, and named after astronomer Jean Chacornac.
(5496) 1973 NA, is a very eccentric and heavily tilted asteroid, classified as near-Earth object of the Apollo group, approximately 2 kilometers in diameter. It was discovered on 4 July 1973, by American astronomer Eleanor Helin at the U.S. Palomar Observatory in California. At the time of its discovery, it was the most highly inclined minor planet known to exist. It may be the parent body of the Quadrantids.
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.
273P/Pons–Gambart, also called Comet Pons-Gambart, is a periodic comet in a retrograde orbit first discovered on June 21, 1827 by Jean-Louis Pons and Jean-Félix Adolphe Gambart. It has a 186 year orbit and it fits the classical definition of a Halley-type comet. Its last perihelion was in December 2012 and will next come to perihelion around August 2191.
Comet Latyshev–Wild–Burnham, also known as C/1957 U1, is a faint parabolic comet that was observed during the third week of October 1957. It was the first comet discovered by American astronomer Robert Burnham, Jr., which he co-discovered alongside Turkmen astronomer, Ivan N. Latyshev, and Swiss astronomer, Paul Wild.
CAMS is a NASA-sponsored international project that tracks and triangulates meteors during night-time video surveillance in order to map and monitor meteor showers. Data processing is housed at the Carl Sagan Center of the SETI Institute in California, USA. Goal of CAMS is to validate the International Astronomical Union's Working List of Meteor Showers, discover new meteor showers, and predict future meteor showers.
C/1939 H1 (Jurlof–Achmarof–Hassel) is a long-period comet discovered on 15 April 1939. The comet was discovered by many observers independently but the first reports were those of Olaf Hassel, Achmarof, and Jurlof. The comet had a magnitude of 3 upon discovery.
C/1911 N1 (Kiess) is a non-periodic comet discovered by Carl Clarence Kiess on 6 July 1911. The comet has been identified as the parent body of the Aurigids meteor shower.
C/1907 G1 (Grigg–Mellish) is a long-period comet discovered independently by John Grigg and John E. Mellish in April 1907. The comet has been identified as the parent body of the delta Pavonids meteor shower.
C/1739 K1 is a non-periodic comet that was discovered by Italian astronomer Eustachio Zanotti in 1739. It is the parent body of the Leo Minorids meteor shower.
Comet Haneda–Campos, formally designated as D/1978 R1, was a periodic comet with a 5.97-year elliptical orbit around the Sun. It was never successfully recovered during its 1984 and 1991 apparitions, and is now considered lost.
C/1853 G1 (Schweizer) is a long period comet discovered by Kaspar Gottfried Schweizer on 5 April 1853. The comet has an orbital period of about 780 years and has been associated with two weak meteor showers.
C/1864 N1 (Tempel) is a non-periodic comet discovered by Wilhelm Tempel on 5 July 1864. It was the first comet whose spectrum was analysed.
