NGC 262 (also known as Markarian 348) is the largest known spiral galaxy, [5] located in the constellation Andromeda. [1] It is a Seyfert 2 spiral galaxy located 287 million light years away. [2] It was discovered on 17 September 1885 by Lewis A. Swift. [4] According to A.M. Garcia, NGC 262 is a member of the NGC 315 Group (also known as LGG 14).

Listed below are galaxies with diameters greater than 700,000 light-years. This list uses the mean cosmological parameters of the Lambda-CDM model based on results from the 2015 Planck collaboration, where H 0 = 67.74 km/s/Mpc, Ω Λ = 0.6911, and Ω m = 0.3089. [3]
NGC 266 is located at a distance of 197 megalight-years from the Milky Way. [4] It was discovered on September 12, 1784, by William Herschel . [ 5 ] The form of this barred galaxy is described by its morphological classification of SB(rs)ab, [ 4 ] which indicates a quasi-ring-like structure (rs) and moderate-to-tightly wound spiral arms (ab).
A image of the Cone nebula and the molecular cloud surrounding it This image was taken from the Mount Lemmon SkyCenter Schulman Telescope. The Cone Nebula is an H II region in the constellation of Monoceros. It was discovered by William Herschel on December 26, 1785, at which time he designated it H V.27.
NGC 2626 is a reflection nebula, emission nebula, and absorption nebula in the constellation Vela. [ 4 ] [ 5 ] It is mostly illuminated by B1 star CD-40 4432 and ionized by the O8 quadruple star system HD 73882 , together with other stars.
