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 NaNMpc. In addition, eight non redshift measurements give a distance of NaNabbr=onNaNabbr=on.^[2] The galaxy was discovered by German-British astronomer William Herschel on 13 September 1784).^[3]

The SIMBAD database lists NGC 735 as a radio galaxy.^[4]
