NGC 5671
Galaxy in the constellation Ursa Minor
From Wikipedia, the free encyclopedia
NGC 5671 is a large barred spiral galaxy in the constellation of Ursa Minor. Its velocity with respect to the cosmic microwave background is 9,058±43 km/s, which corresponds to a Hubble distance of 435.7 ± 30.6 Mly (133.59 ± 9.39 Mpc).[1] However, five non-redshift measurements give a closer mean distance of 353.75 ± 10.07 Mly (108.460 ± 3.086 Mpc).[2] It was discovered by German-British astronomer William Herschel on 6 May 1791.[3][4]
