List Of Long-period Comets
The following list is of comets with very long orbital periods, defined as between 200 and 1000 years. These comets come from the Kuiper belt and scattered disk, beyond the orbit of Pluto, with possible origins in the Oort cloud for many. For comets with an orbital period of over 1000 years, see the List of near-parabolic comets. See also * List of comets by type * List of hyperbolic comets * List of periodic comets * List of numbered comets This is a list of periodic comets that were numbered by the Minor Planet Center after having been observed on at least two occasions.

Comet
A comet is an icy, small Solar System body that, when passing close to the Sun, warms and begins to release gases, a process that is called outgassing. This produces a visible atmosphere or coma, and sometimes also a tail. These phenomena are due to the effects of solar radiation and the solar wind acting upon the nucleus of the comet. Comet nuclei range from a few hundred meters to tens of kilometers across and are composed of loose collections of ice, dust, and small rocky particles. The coma may be up to 15 times Earth's diameter, while the tail may stretch beyond one astronomical unit. If sufficiently bright, a comet may be seen from Earth without the aid of a telescope and may subtend an arc of 30° (60 Moons) across the sky. Comets have been observed and recorded since ancient times by many cultures and religions. Comets usually have highly eccentric elliptical orbits, and they have a wide range of orbital periods, ranging from several years to potentially several mill ...

Great Comet Of 1843
The Great Comet of 1843, formally designated C/1843 D1 and 1843 I, was a long-period comet which became very bright in March 1843 (it is also known as the Great March Comet). It was discovered on February 5, 1843, and rapidly brightened to become a great comet. It was a member of the Kreutz Sungrazers, a family of comets resulting from the breakup of a parent comet (X/1106 C1) into multiple fragments in about 1106. These comets pass extremely close to the surface of the Sun—within a few solar radii—and often become very bright as a result. Perihelion First observed in early February, 1843, it raced toward an incredibly close perihelion of less than 830,000 km on February 27, 1843; at this time it was observed in broad daylight roughly a degree away from the Sun. It passed closest to Earth on March 6, 1843, and was at its greatest brilliance the following day; unfortunately for observers north of the equator, at its peak it was best visible from the Southern Hemispher ...

Holger Thiele
Holger Thiele (September 25, 1878 – June 5, 1946) was a Danish American astronomer and discoverer of minor planets and comets. He was the son of Thorvald Nicolai Thiele (1838–1910), the noted Danish astronomer, actuary and mathematician, after whom the main-belt asteroid 1586 Thiele is named. Holger Thiele is credited by the Minor Planet Center with the discovery of 4 numbered asteroids during 1914–1916. He also discovered the comet C/1906 V1 and calculated the orbits of other comets. He worked at Hamburg-Bergedorf Observatory at Bergedorf, in Hamburg, Germany. In 1912, he immigrated to the United States. In 1917, he started working as a fellow for the University of California at Lick Observatory, near San Jose, California. Holger Thiele died in Alameda County Alameda County ( ) is a List of counties in California, county located in the U.S. state of California.

Michel Giacobini
Michel Giacobini (1873–1938) was a French astronomer. He discovered a number of comets, including 21P/Giacobini-Zinner (parent body of the Giacobinids meteor shower), 41P/Tuttle-Giacobini-Kresak, and 205P/Giacobini. The latter he had discovered at Nice on 4 September 1896, but it was not seen on its return, a little less than 7 years later, and was considered a lost comet and consequently designated D/1896 R2. On 10 September 2008, amateur supernova hunters Koichi Itagaki and Hiroshi Kaneda rediscovered it, on its seventeenth return. He won the Lalande Prize in 1900 and worked at the Nice Observatory until 1910, when he requested a transfer to the Paris Observatory. He was awarded the Valz Prize by the French Academy of Sciences in both 1905 and 1908. In 1903, Giacobinin received the Prix Jules Janssen, the highest award of the Société astronomique de France, the French astronomical society. He volunteered for military service in World War I World War I (28 Ju ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Dillon Perrine
Charles Dillon Perrine (July 28, 1867June 21, 1951) was an American astronomer at the Lick Observatory in California (1893-1909) who moved to Cordoba, Argentina to accept the position of Director of the Argentine National Observatory (1909-1936). The Cordoba Observatory under Perrine's direction made the first attempts to prove Einstein's theory of relativity by astronomical observation of the deflection of starlight near the Sun during the solar eclipse of October 10, 1912 in Cristina (Brazil), and the solar eclipse of August 21, 1914 at Feodosia, Crimea, Russian Empire. Rain in 1912 and clouds in 1914 prevented results. In 1897 he was awarded the Lalande Prize and gold medal by the Paris Academy of Sciences given each year ″to the person who makes the most outstanding observation ... to further the progress of Astronomy, in France or elsewhere.″. He served as President of the Astronomical Society of the Pacific in 1902, was elected an Associate of the Royal Astronomical Soci ...

Walter Frederick Gale
Walter Frederick Gale (27 November 1865 – 1 June 1945) was an Australian banker. Gale was born in Paddington, Sydney, New South Wales. He had a strong interest in astronomy and built his first telescope in 1884. He discovered a number of comets, including the lost periodic comet 34D/Gale. He also discovered five southern double stars with the prefix GLE, and several dark sky objects, including the planetary nebula, IC 5148 in Grus. In 1892, he described oases and canals on Mars. He was awarded the Jackson-Gwilt Medal of the Royal Astronomical Society in 1935 for "discoveries of comets and his work for astronomy in New South Wales." A crater on Mars, Gale Crater, was named in his honour. It was selected as the 2012 landing site for the Curiosity Rover ''Curiosity'' is a car-sized Mars rover designed to explore the Gale crater on Mars as part of NASA's Mars Science Laboratory (MSL) mission.

William Robert Brooks
William Robert Brooks (June 11, 1844 – May 3, 1921) was a British-born American astronomer, mainly noted as being one of the most prolific discoverers of new comets of all time, second only to Jean-Louis Pons. Early life William Robert Brooks was born in Maidstone, England, the son of Caroline (''née'' Wickings) and William Brooks, a Baptist minister who emigrated to Marion, New York. He developed his interest in astronomy during a boyhood voyage to Australia, when he observed a navigator making measurements with a sextant. The following year, he built his very first telescope at the age of 14. Using his own diagrams and sketches, Brooks have his first public lecture at the age of 17 at his fathers church. As a young man he worked in the Shepherd Iron Works in Buffalo, New York, gaining considerable mechanical and draughtsmanship skills: he went on to become a portrait photographer in Phelps before turning his attention to astronomy full-time. Brooks had a good knowledge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
C/1882 R1
The Great Comet of 1882 formally designated 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 of the Sun's photosphere at perihelion. The comet was bright enough to be visible next to the Sun in the daytime sky at its perihelion. Discovery The comet appeared in the morning skies of September 1882. Reports suggest that it was first seen as early as 1 September 1882, from the Cape of Good Hope as well as the Gulf of Guinea, and over the next few days many observers in the southern hemisphere reported the new comet. The first astronomer to record observations of the comet was W. H. Finlay, the Chief Assistant at the Royal Observatory in Cape Town, South Africa. Finlay's observation on 7 September at 16h GMT was also an independent discovery, and he reported that the comet had an apparent magnitude of about 3, and a tail about a degree in length. The comet b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

C/1861 J1
The Great Comet of 1861, formally designated C/1861 J1 and 1861 II, is a long-period comet that was visible to the naked eye for approximately 3 months. It was categorized as a great comet—one of the eight greatest comets of the 19th century. It was discovered by John Tebbutt of Windsor, New South Wales, Australia, on May 13, 1861, with an apparent magnitude of +4, a month before perihelion (June 12). It was not visible in the northern hemisphere until June 29, but it arrived before word of the comet's discovery. On June 29, 1861, Comet C/1861 J1 passed 11.5 degrees (23 Sun-widths) from the Sun. (Observer Location:500) On the following day, June 30, 1861, the comet made its closest approach to the Earth at a distance of . During the Earth close approach, the comet was estimated to be between magnitude 0 and −2 with a tail of over 90 angular degrees. As a result of forward scattering, C/1861 J1 even cast shadows at night (Schmidt 1863; Marcus 1997). During the night of June ...

C/1861 G1
Comet C/1861 G1 (Thatcher) is a long-period comet with roughly a 415-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 from the Earth on 1861-May-05 and last came to perihelion (closest approach to the Sun) on 1861-Jun-03. C/1861 G1 is listed as a long-period "non-periodic comet" because it has not yet been observed at two perihelion passages. When it is seen to come back around 2283, it should receive the P/ designation. The comet is the parent body of the April Lyrids meteor shower.

Christian Heinrich Friedrich Peters
Christian Heinrich Friedrich Peters (September 19, 1813 – July 18, 1890) was a German–American university teacher and astronomer at the Litchfield Observatory of Hamilton College, New York, and a pioneer in the study and visual discovery of asteroids. His name is often given as . Biography He was born in Koldenbüttel in Schleswig, then part of Denmark but later part of Germany, and later studied under Carl Friedrich Gauss. His younger brother was the German explorer Wilhelm Peters. Peters spoke many languages and gravitated to Italy at the time of the Italian unification. His association with radical groups brought him to the attention of authorities, and he fled to the Ottoman Empire, where he became a government advisor. At the suggestion of the resident U.S. consul, he emigrated to the United States in 1854. In 1874, Peters headed a United States Naval Observatory expedition to Queenstown, New Zealand, to observe the Transit of Venus. The visit is marked with a pla ...
