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 potential parent body of the Gamma Normids meteor shower (alongside C/1864 R1). [4]

Discovery and observations

William Robert Brooks spotted a new comet on the morning of 17 October 1893 from his observatory in Geneva, New York. [1] At the time of discovery, it was a 7th-magnitude object located within the constellation Virgo. One day later, Edward E. Barnard made his follow-up observations of the comet, noting it has a deformed tail about 4 degrees long. [1] Barnard continued his photographic sessions of the comet throughout November 1893, documenting its changes in structure. [5] It was last observed by Herbert C. Wilson on the evening of 26 January 1894. [6]

<span class="mw-page-title-main">Comet Encke</span> Periodic comet with 3-year orbit

Comet Encke, or Encke's Comet, is a periodic comet that completes an orbit of the Sun once every 3.3 years. Encke was first recorded by Pierre Méchain on 17 January 1786, but it was not recognized as a periodic comet until 1819 when its orbit was computed by Johann Franz Encke. Like Halley's Comet, it is unusual in its being named after the calculator of its orbit rather than its discoverer. Like most comets, it has a very low albedo, reflecting only 4.6% of the light its nucleus receives, although comets generate a large coma and tail that can make them much more visible during their perihelion. The diameter of the nucleus of Encke's Comet is 4.8 km.

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.

The Great Comet of 1882, formally designated as C/1882 R1, 1882 II, and 1882b, was a comet which became very bright in September 1882. It was a member of the Kreutz Sungrazers, a family of comets which pass within 1 R of the Sun's photosphere at perihelion.

<span class="mw-page-title-main">8P/Tuttle</span> Periodic comet with 13 year orbit

8P/Tuttle is a periodic comet with a 13.6-year orbit. It fits the classical definition of a Jupiter-family comet with an orbital period of less than 20 years, but does not fit the modern definition of. Its last perihelion passage was 27 August 2021 when it had a solar elongation of 26 degrees at approximately apparent magnitude 9. Two weeks later, on September 12, 2021, it was about 1.8 AU (270 million km) from Earth which is about as far from Earth as the comet can get when the comet is near perihelion.

169/NEAT is a periodic comet in the Solar System. It is the parent body of the alpha Capricornids meteor shower in Late July. 169/NEAT may be related to comet P/2003 T12 (SOHO). 169P is a low activity comet roughly a few kilometers in diameter. It could have originated from the main asteroid belt.

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.

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.

Comet Mellish, also known formally as C/1915 C1, is one of five comets discovered by American astronomer John E. Mellish. It is a hyperbolic comet that reached perihelion on July 17, 1915. However, just two months earlier, Edward E. Barnard had reported the comet had splitted into three distinct objects in May 12, later increasing to four by May 24.
