NGC 6047 has a peculiar morphology [5] [8] [9] which suggests it has undergone a recent merger. [6] [7] [10] It may be interacting with NGC 6045 which lies around ~320,000  ly (97  kpc ) away. [8] NGC 6047 has two radio jets [6] [7] and is classified as a FR I radio galaxy. [9] The jets appear to have a Z-shaped structure. [5]
