NGC 3689 is an intermediate spiral galaxy in the constellation of Leo. Its velocity with respect to the cosmic microwave background is 3049 ± 22 km/s, which corresponds to a Hubble distance of 44.97 ± 3.16 Mpc (~147 million light-years). However, 16 non-redshift measurements give a closer distance of 39.350 ± 2.088 Mpc (~128 million light-years). The galaxy was discovered by German-British astronomer William Herschel on 6 April 1785.
NGC 3689 is a radio galaxy, i.e. it has giant regions of radio emission extending well beyond its visible structure.
