NGC 5162 is a very large spiral galaxy in the constellation of Virgo. Its velocity with respect to the cosmic microwave background is 7125 ± 20 km/s, which corresponds to a Hubble distance of 342.8 ± 24.0 Mly (105.09 ± 7.36 Mpc).[1] In addition, 11 non redshift measurements give a distance of 303.71 ± 12.41 Mly (93.118 ± 3.806 Mpc).[2] The galaxy was discovered by German-British astronomer William Herschel on 15 March 1784.[3] It was also observed by Lewis Swift on 19 April 1887, resulting in the galaxy being included twice in the New General Catalogue, as both NGC 5162 and NGC 5174.[3]
The SIMBAD database lists NGC 5162 as a LINER galaxy, i.e. a galaxy whose nucleus has an emission spectrum characterized by broad lines of weakly ionized atoms.[4] NGC 5162 is a field galaxy, i.e. it does not belong to a larger galaxy group or cluster and hence is gravitationally alone.[5]
