NGC 2320 is an elliptical galaxy in the constellation of Lynx. Its velocity with respect to the cosmic microwave background is 6,020±16 km/s, which corresponds to a Hubble distance of 289.6 ± 20.3 Mly (88.80 ± 6.22 Mpc).^[1] However, 14 non-redshift measurements give a closer mean distance of 278.44 ± 19.72 Mly (85.371 ± 6.045 Mpc).^[2] It was discovered by German-British astronomer William Herschel on 28 December 1790.^[3]

NGC 2320 is a radio galaxy, i.e. it has giant regions of radio emission extending well beyond its visible structure.^[4][5]

HDC 426 Group

NGC 2320 is a member of a group of galaxies known as [CHM2007] HDC 426. This group contains 18 galaxies, including NGC 2315, NGC 2321 [fr], NGC 2322 [fr], NGC 2326, NGC 2332 [fr], NGC 2340, IC 458 [de], and IC 465 [de].^[6][7] NGC 2320 is also a member of the galaxy cluster Abell 569.^[8][9]

Supernova

One supernova has been observed in NGC 2320:

• SN 2000B (Type Ia, mag. 16.5) was discovered by French amateur astronomer Pierre Antonini on 11 January 2000.^[10][11][12]
