NGC 5123 is a spiral galaxy in the constellation of Canes Venatici. 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]
