NGC 2 is an intermediate spiral galaxy with the morphological type of Sab, located in the constellation of Pegasus. NGC 2 was discovered by Lawrence Parsons, 4th Earl of Rosse on 20 August 1873." [3]
NGC 2 was first observed by Lawrence Parsons, 4th Earl of Rosse on 24 August 1873, and was described as "very faint, small, south of GC 1." [3]
NGC 2 is located about 345 million light-years from the Solar System, with a magnitude of +14.2, while the distance to NGC 1 is 210 million light-years. Although visually close in the sky, NGC 1 and NGC 2 are at very different distances; were they stars, they would be referred to as an "optical double" as seen from Earth.
AGC 102559, a spiral galaxy 60,000 light-years in diameter, is the closest galaxy to NGC 2, only 1.8 million light-years from it. Although it is quite close to NGC 1, the latter is closer and unrelated to NGC 2.
NGC 2 is a spiral galaxy with a diameter of about 60 thousand light-years, smaller than the size of the Milky Way. [4]
NGC 2 is first cataloged as GC 6246, an addendum to Dreyer's 1877 Supplement to the General Catalogue of Nebulae And Clusters of Stars. The object is cataloged as UGC 59, PGC 567, CGCG 478–027, and MCG +04-01-026.
NGC 1 is an intermediate spiral galaxy of the morphological type Sbc, located in the constellation of Pegasus. It was discovered on 30 September 1861 by Heinrich d'Arrest.
NGC 3 is a lenticular galaxy with the morphological type of S0, located in the constellation of Pisces. Other sources classify NGC 3 as a barred spiral galaxy as a type of SBa. It was discovered on November 29, 1864, by Albert Marth.
NGC 47 is a barred spiral galaxy in the constellation Cetus, discovered in 1886 by Ernst Wilhelm Leberecht Tempel. Its alternate name NGC 58 is due to the observation by Lewis Swift, who was unaware that Tempel had already discovered the celestial object earlier. It appears as a small, faint spiral nebula with a bright core and is slightly oval.
NGC 1260 is a spiral or lenticular galaxy located 250 million light years away from earth in the constellation Perseus. It was discovered by astronomer Guillaume Bigourdan on 19 October 1884. NGC 1260 is a member of the Perseus Cluster and forms a tight pair with the galaxy PGC 12230. This galaxy is dominated by a population of many old stars.
NGC 166 is a spiral galaxy located around 2.6 million light-years away in the constellation Cetus, with an apparent magnitude of 15.18. It was discovered by Francis Preserved Leavenworth in 1886.
NGC 174 is a barred spiral or lenticular galaxy around 159 million light-years away in the constellation Sculptor. It was discovered on 27 September 1834 by astronomer John Herschel.
NGC 218, also known as UGC 480, is a spiral galaxy located approximately 500 million light-years from the Sun in the constellation Andromeda. It was discovered on October 17, 1876 by Édouard Stephan, and is interacting with the galaxy PGC 2726.
LEDA 135657 is a distant low surface brightness spiral galaxy located about 570 million light-years away in the constellation Cetus. It has an estimated diameter of 97,000 light-years.
NGC 7043 Is a barred spiral galaxy located about 200 million light-years away in the constellation of Pegasus. NGC 7043 is part of a pair of galaxies that contains the galaxy NGC 7042. It has an estimated diameter of 73,100 light-years. NGC 7043 was discovered by astronomer Albert Marth on August 18, 1863.
NGC 7047 is an intermediate spiral galaxy located about 270 million light-years away in the constellation of Aquarius. NGC 7047 is also classified as a LINER-type galaxy. NGC 7047 has an estimated diameter of 127,350 light years. It was discovered by French astronomer Édouard Stephan on August 20, 1873. In 2009 a supernova was found in NGC 7047.
ESO 198-13 is a ring galaxy with multiple ring-like structures located about 240 million light-years away in the constellation Eridanus.
PGC 44691 is a spiral galaxy located about 350 million light-years away in the constellation Coma Berenices. It belongs to a galaxy cluster known as the Coma Cluster. In 1994, the Hubble Space Telescope observed PGC 44691 and the nearby elliptical galaxy NGC 4881 to infer the distance to the Coma Cluster.
NGC 486, also occasionally referred to as LEDA 1281966 or GC 275, is a spiral galaxy in the constellation Pisces. NGC 486 was discovered on December 6, 1850 by Irish engineer Bindon Blood Stoney.
NGC 492, also occasionally referred to as PGC 4976 or GC 280, is a barred spiral galaxy in the constellation Pisces. It is located approximately 590 million light-years from Earth and was discovered on December 6, 1850 by Irish engineer Bindon Blood Stoney. Although John Dreyer, creator of the New General Catalogue, credits the discovery to astronomer William Parsons, 3rd Earl of Rosse, he notes that many of his claimed discoveries were made by one of his assistants. In the case of NGC 492, the discovery was made by Bindon Stoney, who discovered it along with NGC 486, NGC 490 and NGC 500 during his observation of NGC 488 using Lord Rosse's 72" telescope.
NGC 4519 is a barred spiral galaxy located about 70 million light-years away in the constellation Virgo. NGC 4519 was discovered by astronomer William Herschel on April 15, 1784. It has a companion galaxy known as PGC 41706 and is a member of the Virgo Cluster.
NGC 806 is a spiral galaxy approximately 166 million light-years away from Earth in the constellation Cetus. It was discovered by American astronomer Lewis A. Swift on November 1, 1886 with the 16" refractor at Warner Observatory.
NGC 501, also occasionally referred to as PGC 5082 or GC 284, is an elliptical galaxy in the constellation Pisces. It is located approximately 224 million light-years from the Solar System and was discovered on 28 October 1856 by Irish astronomer R. J. Mitchell.
NGC 6040 is a spiral galaxy located about 550 million light-years away in the constellation Hercules. NGC 6040 was discovered by astronomer Édouard Stephan on June 27, 1870. NGC 6040 is interacting with the lenticular galaxy PGC 56942. As a result of this interaction, NGC 6040's southern spiral arm has been warped in the direction toward PGC 56942. NGC 6040 and PGC 56942 are both members of the Hercules Cluster.
NGC 2936 is an interacting spiral galaxy located at a distance of 326 million light years, in the constellation Hydra. NGC 2936 is interacting with elliptical galaxy NGC 2937, located just beneath it. They were both discovered by Albert Marth on Mar 3, 1864. To some astronomers, the galaxy looks like a penguin or a porpoise. NGC 2936, NGC 2937, and PGC 1237172 are included in the Atlas of Peculiar Galaxies as Arp 142 in the category "Galaxy triplet".
NGC 5395 is an interacting spiral galaxy located at a distance of 160 million light years, but receding away from the Earth at 3511 kilometers per second, in the constellation Canes Venatici. It was discovered by William Herschel on May 16, 1787. NGC 5395 and NGC 5394 are included in the Atlas of Peculiar Galaxies as Arp 84 in the category "Spiral galaxies with large high surface brightness companions".
