NGC 5090 and NGC 5091 are a set of galaxies approximately 160 million light-years (50 million parsecs) away in the constellation Centaurus.[1] They are in the process of colliding and merging with some evidence of tidal disruption of NGC 5091.[2]
NGC 5090 is an elliptical galaxy while NGC 5091 is a barred spiral galaxy.[1] The radial velocity of the nucleus of NGC 5090 has been measured at 3,185 km/s (1,979 mi/s), while NGC 5091 has a radial velocity of 3,429 km/s (2,131 mi/s).[2] NGC 5090 is associated with the strong, double radio source PKS 1318-43.[2]
One supernova has been observed in NGC 5090: SN 1981C (type unknown, mag. 14.5).[3]
