NGC5162 is a very large spiral galaxy in the constellation of Virgo. Its velocity with respect to the cosmic microwave background is 7125 ± 20km/s, which corresponds to a Hubble distance of NaNMpc. In addition, 11 non redshift measurements give a distance of NaNabbr=onNaNabbr=on.[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.
The SIMBAD database lists NGC5162 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]
Two supernovae have been observed in NGC 5162. Kōichi Itagaki discovered SN2007cd (type unknown, mag. 17.5) on 27 April 2007.[6] The Xingming Observatory Sky Survey discovered SN2024aawh (typeII, mag. 18.11) on 10 November 2024.[7]
