NGC 3936


NGC 3936 is a barred spiral galaxy in the constellation of Hydra. Its velocity with respect to the cosmic microwave background is 2,357 ± 24km/s, which corresponds to a Hubble distance of 34.76 ± 2.46Mpc. It was discovered by British astronomer John Herschel on 24 March 1835.
As of July 2024, 26 non-redshift measurements give a distance of 20.912 ± 2.969Mpc, 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 NGC3936.

NGC 3936 Group

NGC 3936 is the largest of a small group of four galaxies named after it. The other three galaxies in the NGC 3936 group are NGC 3885, ESO 440-4, and ESO 440-11.
