NGC 1042 is a spiral galaxy located in the constellation Cetus. It was discovered on 10 November 1885 by American astronomer Lewis Swift.[2] The galaxy has an apparent magnitude of 14.0.
NGC 1042 is a low-luminosity active galaxy.[3][4] Furthermore, its luminosity class is III–IV and it has a broad HI line.[5] It is known that NGC 1042 also hosts an intermediate-mass black hole in its center.[6]
NGC 1042 contains an ultraluminous X-ray source called NGC 1042 ULX1.[7]
