NGC 3936
Galaxy in the constellation Cetus
From Wikipedia, the free encyclopedia
NGC 3936 is a barred spiral galaxy in the constellation of Hydra. Its velocity with respect to the cosmic microwave background is 2,357 ± 24 km/s, which corresponds to a Hubble distance of 34.76 ± 2.46 Mpc (~113 million light-years).[1] It was discovered by British astronomer John Herschel on 24 March 1835.[2]

As of July 2024, 26 non-redshift measurements give a distance of 20.912 ± 2.969 Mpc (~68.2 million light-years),[3] which is well outside the Hubble distance values. But, since this galaxy is relatively close to the Local Group, it is very likely that this value is closer to the true distance to NGC 3936.
