NGC 4185 is a large spiral galaxy in the constellation of Coma Berenices. Its velocity with respect to the cosmic microwave background is 4,178±21 km/s, which corresponds to a Hubble distance of 201.0 ± 14.1 Mly (61.63 ± 4.33 Mpc).[1] Additionally, three non-redshift measurements give a farther mean distance of 214.61 ± 0.33 Mly (65.800 ± 0.100 Mpc).[2] It was discovered by German-British astronomer William Herschel on 11 April 1785.[3][4]
NGC 4195 is a LINER galaxy, i.e. a galaxy whose nucleus has an emission spectrum characterized by broad lines of weakly ionized atoms.[5][6]
Supernova
One supernova has been observed in NGC 4185:
- SN 1982C (type unknown, mag. 17.5) was discovered by Hungarian astronomer Miklós Lovas on 22 March 1982.[9][10]
