NGC 1201 is a lenticular galaxy in the constellation of Fornax. Its velocity with respect to the cosmic microwave background is 1,531±16 km/s, which corresponds to a Hubble distance of 73.6 ± 5.3 Mly (22.58 ± 1.61 Mpc).[1] However, 10 non-redshift measurements give a closer mean distance of 63.37 ± 4.96 Mly (19.430 ± 1.520 Mpc).[2] It was discovered by German-British astronomer William Herschel on 26 October 1785.[3][4]
NGC 1201 has a possible active galactic nucleus, i.e. it has a compact region at the center of a galaxy that emits a significant amount of energy across the electromagnetic spectrum, with characteristics indicating that this luminosity is not produced by the stars.[5][6]
NGC 1255 group
NGC 1201 is a member of the NGC 1255 group (also known as LGG 86), which contains at least 5 galaxies, including NGC 1255, NGC 1302, ESO 481-14, and ESO 481-18.[7][8]
Supernova
One supernova has been observed in NGC 1201:
- SN 2003hv (Type Ia, mag. 12.5) was discovered by LOTOSS (Lick Observatory and Tenagra Observatory Supernova Searches) on 2 April 2003.[9][10] It reached magnitude 12.3, making it the brightest supernova of 2003.[11]
