NGC 1262
Galaxy in the constellation of Eridanus
From Wikipedia, the free encyclopedia
NGC 1262 is a barred spiral galaxy[4] located in the constellation Eridanus.[5] This galaxy was formerly believed to be the most distant object in the New General Catalogue with redshift and distance estimates placing it at z = 0.116 and hence roughly 507.0 megaparsecs (1,650 million light-years) from Earth,[1] corresponding to a large isophotal diameter of about 125.59 kiloparsecs (410,000 light-years) based on its D25.0 apparent dimension, making it nearly five times larger than the Milky Way and one of the largest spiral galaxies.[1] However, in 2023 using data from Ann Isaacs from the University of Minnesota, Stephen Odewahn from the McDonald Observatory used new radial velocity calculations with a new estimate of 15,169 km/s, which corresponds to a lower redshift of z = 0.0506 and hence a light-travel distance of 686 million light-years (210.3 megaparsecs), placing NGC 1262 nowhere near the most distant NGC galaxy and resulting a rather lower isophotal diameter.[2] It was discovered by astronomer Francis Leavenworth on November 12, 1885.[4]
