NGC 4141
Galaxy in the constellation Ursa Major
From Wikipedia, the free encyclopedia
NGC 4141 is a barred spiral galaxy in the constellation of Ursa Major. Its velocity with respect to the cosmic microwave background is 2,051±11 km/s, which corresponds to a Hubble distance of 98.7 ± 6.9 Mly (30.25 ± 2.12 Mpc).[1] However, two non-redshift measurements give a farther mean distance of 133 ± 11 Mly (40.8 ± 3.3 Mpc).[2] It was discovered by German-British astronomer William Herschel on 17 April 1789.[3][4]
