NGC 5374 is a barred spiral galaxy in the constellation of Virgo. Its velocity with respect to the cosmic microwave background is 4,612±19 km/s, which corresponds to a Hubble distance of 221.9 ± 15.6 Mly (68.02 ± 4.77 Mpc).[1] Additionally, seven non-redshift measurements give a similar mean distance of 224.16 ± 13.31 Mly (68.729 ± 4.081 Mpc).[2] It was discovered by German-British astronomer William Herschel on 12 May 1793.[3][4]

NGC 5374 is a is a radio galaxy, i.e. it has giant regions of radio emission extending well beyond its visible structure.[5]

NGC 5374 group

According to A. M. Garcia, NGC 5374 is the namesake of a group of galaxies. The NGC 5374 group (also known as LGG 368) contains at least eight galaxies, including NGC 5382, NGC 5384, NGC 5386, NGC 5417, NGC 5418, NGC 5434, and UGC 8906.[6]

Supernovae

Three supernovae have been observed in NGC 5374:

  • SN 2003bl (Type II, mag. 18.4) was discovered by LOTOSS (Lick Observatory and Tenagra Observatory Supernova Searches) on 2 March 2003.[7][8]
  • SN 2010do (Type Ic, mag. 17.2) was discovered by L. A. G. "Berto" Monard on 2 June 2010.[9][10]
  • SN 2016P (Type Ic-BL, mag. 16) was discovered by Grzegorz Duszanowicz and Michal Zolnowski on 19 January 2016.[11]
