NGC735 is a spiral galaxy in the constellation of Triangulum. Its velocity with respect to the cosmic microwave background is 4374 ± 18km/s, which corresponds to a Hubble distance of . In addition, eight non redshift measurements give a distance of . The galaxy was discovered by German-British astronomer William Herschel on 13 September 1784.
NGC 735 has a possible active galactic nucleus, i.e. it has a compact region at the center of a galaxy that emits a significant amount of energy across the electromagnetic spectrum, with characteristics indicating that this luminosity is not produced by the stars.
