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.
Kaspar Gottfried Schweizer found the comet near rho Aquilae while observing from Moscow and described it as small and round, about 3 arcminutes across, with no tail. [3] The comet then was moving towards Earth and thus was moving slowly in the sky. The closest approach to Earth took place on 29 April, at a distance of 0.084 AU. That day the comet moved 24 degrees in the sky. [2]
After that it appeared in the southern hemisphere. Its tail was reported to be up to 10 degrees long and the nucleus was as bright as a third or fourth magnitude star. On May 1 the comet was reported to be of first magnitude. The comet faded rapidly and by May it was no longer visible with naked eye. Perihelion took place on 10 May. The comet was last detected on 11 June 1853. [2]
The minimum orbital intersection distance of the comet with Earth is 0.07 AU. The comet has been associated with the weak γ Aquilids meteor shower, which peaks on 4 May. [4] A second meteor shower associated with the comet is the 52 Herculids. That shower could be the same as the R Lyrids. [5]
12P/Pons–Brooks is a periodic comet with an orbital period of 71 years. Comets with an orbital period of 20–200 years are referred to as Halley-type comets. It is one of the brightest known periodic comets, reaching an absolute visual magnitude of about 5 in its approach to perihelion. Comet Pons-Brooks was conclusively discovered at Marseilles Observatory in July 1812 by Jean-Louis Pons, and on its next appearance in 1883 by William Robert Brooks. However it has been confirmed 12P/Pons–Brooks was observed before the 19th century.
(5335) Damocles, provisional designation 1991 DA, is a centaur and the namesake of the damocloids, a group of minor planets which may be inactive nuclei of the Halley-type and long-period comets. It was discovered on 18 February 1991, by Australian astronomer Robert McNaught at Siding Spring Observatory in Australia. It is named after Damocles, a figure of Greek mythology.
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.
C/2007 W1 (Boattini) is a non-periodic comet discovered on 20 November 2007, by Andrea Boattini at the Mt. Lemmon Survey. At the peak the comet had an apparent magnitude around 5.
The Great Comet of 1901, sometimes known as Comet Viscara, formally designated C/1901 G1, was a comet which became bright in the spring of 1901. Visible exclusively from the southern hemisphere, it was discovered on the morning of April 12, 1901 as a naked-eye object of second magnitude with a short tail. On the day of perihelion passage, the comet's head was reported as deep yellowish in color, trailing a 10-degree tail. It was last seen by the naked eye on May 23.
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.
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.
Comet van Gent–Peltier–Daimaca, formally designated as C/1943 W1, is a non-periodic comet with a rather peculiar discovery. It was independently discovered by four astronomers, however the established system of naming comets by the International Astronomical Union only recognizes the names of the first three people who observed it.
C/1979 Y1 (Bradfield), also known as Comet 1979X and 1979l, is a long period comet discovered by William A. Bradfield on 24 December 1979. The comet has an orbital period of 308 ± 6 years and last passed perihelion on 21 December 1979. It is considered to be the parent body of the July Pegasids meteor shower. It is expected to next come to perihelion around 2287.
C/1917 F1 (Mellish), also known as Comet 1917Ι and 1917a, is a Halley-type comet discovered by John E. Mellish on 19 March 1917. The comet has an orbital period of 143 years and last passed perihelion on 11 April 1917. It is the parent body of the December Monocerotids and has also been suggested to be the parent body of daytime kappa Leonids, April ρ-Cygnids, November Orionids, and Canis-Minorids 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/1961 T1 (Seki) is a long-period comet discovered by Tsutomu Seki on 10 October 1961. The comet has been identified as the parent body of the December ρ-Virginids meteor shower.
Comet Brooks, formally designated as C/1893 U1, is a non-periodic comet that became visible through telescopes in late 1893. This comet might be the parent body of the Gamma Normids meteor shower.
Comet Borrelly–Brooks, formal designation C/1900 O1, is a hyperbolic comet that was seen throughout the latter half of 1900.
C/1948 L1 (Honda–Bernasconi) is a non-periodic comet discovered on 3 June 1948. The comet was discovered by Minoru Honda and independently found by Giovanni Bernasconi the next day.
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.
C/1862 N1 (Schmidt), sometimes refered to as C/1862 N1 (Schmidt–Temple), is a non-periodic comet discovered by Johann Friedrich Julius Schmidt on 2 July 1862.
