NGC 1419 is anelliptical galaxy[4] located 62 million light years away[2] in the constellation ofEridanus. The galaxy was discovered by astronomerJohn Herschel on October 22, 1835,[5] and is a member of theFornax Cluster.[6] NGC 1419 is a host to asupermassive black hole with an estimated mass of 25 millionsolar masses.[7]

155 knownglobular clusters have been observed surrounding NGC 1419,[8] along with 21planetary nebulae. These planetary nebulae reveal that the distance to NGC 1419 is approximately 18.9Mpc, while measurements usingsurface brightness fluctuations reveal that NGC 1419 is approximately 22.9 ± 0.9Mpc away. The measurements using planetary nebulae confirm that NGC 1419 is a member of theFornax Cluster.[2]
