IC 2150 is a barred spiral galaxy in the constellation of Columba. Its velocity with respect to the cosmic microwave background is 3,196±7 km/s, which corresponds to a Hubble distance of 153.8 ± 10.8 Mly (47.14 ± 3.30 Mpc).[1] However, 16 non-redshift measurements give a closer mean distance of 140.12 ± 3.45 Mly (42.962 ± 1.057 Mpc).[2] It was discovered by American astronomer Lewis Swift on 31 January 1898.[3]

IC 2150 has a possible active galactic nucleus, i.e. it has a compact region at the center of its galaxy that emits a significant amount of energy across the electromagnetic spectrum, with characteristics indicating that this luminosity is not produced by the stars.[4][5]

Supernovae

Three supernovae have been observed in IC 2150. The first two were discovered simultaneously.
