NGC 7513 is a barred spiral galaxy located in the constellation Sculptor. It is located at a distance of circa 62.5 million light years from Earth, which, given its apparent dimensions, means that NGC 7513 is about 75,000 light years across.[1] It was discovered by Albert Marth on September 24, 1864.[2]

A large star cluster has been found in the nucleus, with an estimated mass of 107.0 M☉.[3] There is circumnuclear dust distributed irregularly.[4]

NGC 7513 is a member of the NGC 7507 galaxy group, named after NGC 7507, along with some smaller galaxies.[5] NGC 7507 is an elliptical galaxy lying at a projected distance of 18 arcminutes.[6]
