Its velocity with respect to the cosmic microwave background is 8,487±14 km/s, which corresponds to a Hubble distance of 408.3 ± 28.6 Mly (125.18 ± 8.76 Mpc).[1] It was discovered by German-British astronomer William Herschel on 9 April 1787.[2] NGC 5123 is a radio galaxy, i.e. it has giant regions of radio emission extending well beyond its visible structure.[3][4] Supernova One supernova has been observed in NGC 5123: SN 2008dz (Type II, mag. 17.4) was discovered by Tim Puckett and Robert Gagliano on 6 July 2008.[5][6] See also List of NGC objects (5001–6000) References 1 2 3 4 5 6 7 8 9 10 11 "Results for object NGC 5123".
