NGC 5185 is a spiral galaxy in the constellation of Virgo. Its velocity with respect to the cosmic microwave background is 7,683±20 km/s, which corresponds to a Hubble distance of 369.6 ± 25.9 Mly (113.32 ± 7.94 Mpc).[1] Additionally, 16 non-redshift measurements give a similar mean distance of 374.23 ± 10.11 Mly (114.738 ± 3.101 Mpc).[2] It was discovered by German-British astronomer William Herschel on 19 March 1787.[3]

NGC 5185 is a Seyfert II galaxy, i.e. it has a quasar-like nucleus with very high surface brightnesses whose spectra reveal strong, high-ionisation emission lines, but unlike quasars, the host galaxy is clearly detectable.[4][5]

LDC 985 Group

NGC 5185 is a member of a group of galaxies known as LDC 985. The other five galaxies in the group are NGC 5181, NGC 5207, NGC 5221, NGC 5222, NGC 5230.[6][7]
