NGC 4589 is an elliptical galaxy located in the Draco constellation. It was discovered by German-British astronomer William Herschel on November 22, 1797. This galaxy lies at a distance of 73.0 million light-years (22.39 Mpc) from the Milky Way, and is receding with a heliocentric radial velocity of 2,002 km/s. It is known by its designations PGC 42139 or UGC 7797.

The morphological classification of NGC 4589 is E2 in the De Vaucouleurs system, Indicating this is an elliptical galaxy with a ratio of 5:4 between the major and minor axes. It is a bright source of X-ray emission and is a LINER-type galaxy. There is a dusty disk that is aligned with the minor axis, which is likely the remnant of a merger with a gas-rich galaxy. NGC 4589 has a large population of globular clusters, estimated at 640±50. A small population of young star clusters with an age of less than a billion years are located in the central region.
