ESO 383-76 (ESO 383-G 076) is an elongated, X-ray luminous supergiant elliptical galaxy, residing as the dominant, brightest cluster galaxy (BCG) of the Abell 3571 galaxy cluster, the sixth-brightest in the sky at X-ray wavelengths.[3] It is located at the distance of 200.6 megaparsecs (654 million light-years) from Earth, and is possibly a member of the large Shapley Supercluster. With a diameter of about 540.89 kiloparsecs (1.76 million light-years), it is one of the largest galaxies known. It also contains a supermassive black hole, one of the most massive known with mass estimates varying from 2 billion M☉ to 28 billion M☉.[4][5]
