NGC 5374
Galaxy in the constellation Virgo
From Wikipedia, the free encyclopedia
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]
