NGC 5854
Galaxy in the constellation Virgo
From Wikipedia, the free encyclopedia
NGC 5854 is a lenticular galaxy in the constellation of Virgo. Its velocity with respect to the cosmic microwave background is 1,851±14 km/s, which corresponds to a Hubble distance of 89.0 ± 6.3 Mly (27.30 ± 1.92 Mpc).[1] However, seven non-redshift measurements give a much closer mean distance of 60.95 ± 6.94 Mly (18.686 ± 2.128 Mpc).[2] It was discovered by German-British astronomer William Herschel on 24 February 1786.[3][4]
