NGC 6045 is a barred spiral galaxy located about 450 million light-years away[2] in the constellation Hercules.[3] NGC 6045 was discovered by astronomer Lewis Swift on June 27, 1886[4] and is a member of the Hercules Cluster.[5][4] It is also a LINER galaxy.[6]

Possible interaction
editNGC 6045 is very luminous in both X-ray[5] and infrared light.[7] This high luminosity in both X-ray and infrared has been suggested to be the result of a starburst event in the galaxy.[5][7] It is thought that starburst events are caused by interactions or mergers with other galaxies.[8][5] Also, NGC 6045 has a warped disk which may be due to an interaction[7] with the elliptical galaxy NGC 6047 which lies around ~320,000 ly (97 kpc) from the galaxy.[5]
