NGC 4411
Galaxy in the constellation Virgo
From Wikipedia, the free encyclopedia
NGC 4411 (also known as NGC 4411A) is a barred spiral galaxy in the constellation of Virgo. Its velocity with respect to the cosmic microwave background is 1,616±24 km/s, which corresponds to a Hubble distance of 77.7 ± 5.5 Mly (23.83 ± 1.70 Mpc).[1] However, five non-redshift measurements give a closer distance of 51.66 ± 4.59 Mly (15.840 ± 1.408 Mpc).[2] It was discovered by German–American astronomer Christian Heinrich Friedrich Peters in 1881.[3] It was also observed by German astronomer Friedrich Karl Arnold Schwassmann on 23 January 1900, resulting in it being listed in the Index Catalogue as IC 3339.[3] There was a longstanding confusion of identification between this galaxy and the neighboring spiral galaxy NGC 4411B.[3]
