NGC 6047 is an elliptical galaxy located about 430 million light-years away[2] in the constellation Hercules.[3] It was discovered by astronomer Lewis Swift on June 27, 1886.[4] NGC 6047 is a member of the Hercules Cluster.[5][6][7]

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]
