NGC 485

NGC 485, also commonly referred to as PGC 4921 or GC 270, is a spiral galaxy in the constellation Pisces.[2] It is located approximately 86 million light-years from Earth[1] and was discovered on January 8, 1828 by astronomer William Herschel.[3] 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".[4]
