NGC 735

NGC 735 is a spiral galaxy in the constellation of Triangulum. Its velocity with respect to the cosmic microwave background is 4374 ± 18 km/s, which corresponds to a Hubble distance of 210.4 ± 14.7 Mly (64.52 ± 4.52 Mpc).^[1] In addition, eight non redshift measurements give a distance of 227.21 ± 7.99 Mly (69.662 ± 2.449 Mpc).^[2] The galaxy was discovered by German-British astronomer William Herschel on 13 September 1784).^[3]
