NGC 1589 is a large spiral galaxy in the constellation of Taurus. Its velocity with respect to the cosmic microwave background is 3,729±9 km/s, which corresponds to a Hubble distance of 179.4 ± 12.6 Mly (55.00 ± 3.85 Mpc).[1] However, three non-redshift measurements give a closer mean distance of 154.38 ± 1.90 Mly (47.333 ± 0.584 Mpc).[2] It was discovered by German-British astronomer William Herschel on 19 December 1783.[3]
