NGC 5082 is a lenticular galaxy in the constellation of Centaurus. Its velocity with respect to the cosmic microwave background is 4,153±46 km/s, which corresponds to a Hubble distance of 199.8 ± 14.3 Mly (61.25 ± 4.38 Mpc).[1] However, three non-redshift measurements give a closer mean distance of 152.97 ± 3.46 Mly (46.900 ± 1.060 Mpc).[2] It was discovered by British astronomer John Herschel on 3 June 1834.[3]
NGC 5082 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.[4][5]
NGC 5082 group
NGC 5082 is a member of a small group of galaxies named after it. The other two galaxies in the NGC 5082 group (also known as LGG 348) are ESO 270-7 (d) and ESO 270-14 (d).[6][7]
Supernova
One supernova has been observed in NGC 5082:
- SN 1958F (type unknown, mag. 16) was discovered by Milton L. Humason on 13 June 1958.[8][9]
