NGC 806 is a spiral galaxy approximately 166 million light-years away from Earth in the constellation Cetus. [1] It was discovered by American astronomer Lewis A. Swift on November 1, 1886 with the 16" refractor at Warner Observatory. [4]
NGC 806 and PGC 3100716 form a pair of galaxies in gravitational interaction. These two galaxies are either colliding or are the result of a collision. [5]
PGC 3100716 is a spiral galaxy with an apparent size of 0.09 by 0.08 arcmin. [1] It was not included in the original version of the New General Catalogue, and was later added as NGC 806-2. [3]
NGC 500 is a type E-SO lenticular galaxy located in the Pisces constellation. It has an apparent size of .8 by .6 arcminutes and an apparent magnitude of 14.2. It was first discovered in 1850 by Bindon Blood Stoney during his time at Birr Castle in Ireland.
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.
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.
NGC 360 is a spiral galaxy located approximately 103 million light-years from the Solar System in the constellation Tucana. It was discovered on 2 November 1834 by John Herschel. Dreyer, creator of the New General Catalogue described the object as "extremely faint, very much extended 145°, very little brighter middle."
NGC 485, also commonly referred to as PGC 4921 or GC 270, is a spiral galaxy in the constellation Pisces. It is located approximately 86 million light-years from Earth and was discovered on January 8, 1828 by astronomer William Herschel. It was later also observed by Heinrich d'Arrest and Herman Schultz. When NGC 485 was originally categorized in the New General Catalogue by John Louis Eil Dreyer in 1888, it was incorrectly described as a "considerably faint, pretty large, round, 8th magnitude star 3 1/2 arcmin to southwest".
NGC 495, also occasionally referred to as PGC 5037, UGC 920 or GC 278, is a barred spiral galaxy in the constellation Pisces. It is located approximately 184 million light-years from the Solar System and was discovered on 12 September 1784 by astronomer William Herschel.
NGC 496, also occasionally referred to as PGC 5037, UGC 927 or GC 288, is a spiral galaxy in the constellation Pisces. It is located approximately 250 million light-years from the Solar System and was discovered on 12 September, 1784 by astronomer William Herschel.
NGC 502, also occasionally referred to as PGC 5034 or UGC 922, is a lenticular galaxy in the constellation Pisces. It is located approximately 113 million light-years from the Solar System and was discovered on 25 September 1862 by German astronomer Heinrich Louis d'Arrest. When the Morphological Catalogue of Galaxies was published between 1962 and 1974, the identifications of NGC 502 and NGC 505 were reversed. In reality, NGC 502 is equal to MGC +01-04-041 and not MCG +01-04-043 as noted in the catalogue.
NGC 503, also occasionally referred to as PGC 5086 or GC 5169, is an elliptical galaxy in the constellation Pisces. It is located approximately 265 million light-years from the Solar System and was discovered on 13 August 1863 by German astronomer Heinrich Louis d'Arrest.
NGC 511, also occasionally referred to as PGC 5103 or UGC 936, is an elliptical galaxy in the constellation Pisces. It is located approximately 499 million light-years from the Solar System and was discovered on 26 October 1876 by French astronomer Édouard Stephan.
NGC 512, also occasionally referred to as PGC 5132 or UGC 944, is a spiral galaxy in the constellation Andromeda. It is located approximately 217 million light-years from the Solar System and was discovered on 17 November 1827 by astronomer John Herschel.
NGC 513, also occasionally referred to as PGC 5174 or UGC 953, is a spiral galaxy in the constellation Andromeda. It is located approximately 262 million light-years from the Solar System and was discovered on 13 September 1784 by astronomer William Herschel.
NGC 515, also occasionally referred to as PGC 5201 or UGC 956, is a lenticular galaxy located approximately 228 million light-years from the Solar System in the constellation Pisces. It was discovered on 13 September 1784 by astronomer William Herschel.
NGC 517, also occasionally referred to as PGC 5214 or UGC 960, is a lenticular galaxy located approximately 188 million light-years from the Solar System in the constellation Pisces. It was discovered on 13 September 1784 by astronomer William Herschel.
NGC 519, also occasionally referred to as PGC 5182 is an elliptical galaxy located approximately 242 million light-years from the Solar System in the constellation Cetus. It was discovered on 20 November 1886 by astronomer Lewis Swift.
NGC 521, also occasionally referred to as PGC 5190 or UGC 962, is a spiral galaxy located approximately 224 million light-years from the Solar System in the constellation Cetus. It was discovered on 8 October 1785 by astronomer William Herschel.
NGC 522, also occasionally referred to as PGC 5218 or UGC 970, is a spiral galaxy located approximately 122 million light-years from the Solar System in the constellation Pisces. It was discovered on 25 September 1862 by astronomer Heinrich Louis d'Arrest.
NGC 525, also occasionally referred to as PGC 5232 or UGC 972 is a lenticular galaxy located approximately 95.6 million light-years from the Solar System in the constellation Pisces. It was discovered on 25 September 1862 by astronomer Heinrich d'Arrest.
NGC 527, also occasionally referred to as PGC 5128 or PGC 5141, is a lenticular galaxy located approximately 259 million light-years from the Solar System in the constellation Sculptor. It was discovered on 1 September 1834 by astronomer John Herschel.
