NGC 1404 is an elliptical galaxy in the Southern constellation Eridanus. It was discovered on November 28, 1837, by the astronomer John Herschel.[5] Based on the tip of the red-giant branch distance indicator, it lies at a distance of approximately 60 million light-years from the Milky Way.[3] It is one of the brightest members of the Fornax Cluster.[6][7]

Characteristics


As usual with most elliptical galaxies, NGC 1404 is rich in globular clusters, with a population of them that has been estimated to be around 725;[8] however it has been proposed it could have lost most of its globular clusters due to gravitational interactions with NGC 1399, the brightest galaxy of the Fornax Cluster.[9]

Studies with the help of the X-ray telescope Chandra show too how ram-pressure stripping caused by the motion of NGC 1404 through Fornax' intracluster medium is stripping this galaxy of its hot gas,[10] leaving behind a large trail.[11]
