NGC 1077 is a spiral galaxy in the constellation Perseus. It was discovered on 16 August 1886 by Lewis A. Swift.[5] It was described as "very faint, pretty large, extended" by John Louis Emil Dreyer, the compiler of the New General Catalogue.[5]

NGC 1077 is a galaxy pair with another galaxy appearing close to it. This galaxy, NGC 1077B, has a recessional velocity of 8529 km/s.[6] This is similar to NGC 1077's recessional velocity of 8964 km/s, so they are assumed to be physically related.[5]
