NGC 3936 is abarred spiral galaxy in theconstellation ofHydra. Its velocity with respect to thecosmic microwave background is 2,357 ± 24 km/s, which corresponds to aHubble distance of 34.76 ± 2.46 Mpc (~113 millionlight-years).[1] It was discovered byBritish astronomerJohn Herschel on 24 March 1835.[2]
As of July 2024, 26non-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 theLocal Group, it is very likely that this value is closer to the true distance to NGC 3936.
NGC 3936 is the largest of a smallgroup of four galaxies named after it. The other three galaxies in the NGC 3936 group (also known asLGG 253) areNGC 3885, ESO 440-4, and ESO 440-11.
Onesupernova has been observed in NGC 3936:SN 2024phv (Type II, mag. 17.3523) was discovered by theDistance Less Than 40 Mpc Survey (DLT40) on 10 July 2024.[4]
