NGC 1373 is a dwarf elliptical galaxy[4] located 61 million light years away[5] in constellation of Fornax. The galaxy was discovered by astronomer John Herschel on November 29, 1837,[6] and is a member of the Fornax Cluster.[7] NGC 1373 is a host to a supermassive black hole with an estimated mass of 4.6 million solar masses.[8]

63 known globular clusters have been observed surrounding NGC 1373,[9] along with 13 observed planetary nebulae.[10]

Physical characteristics

NGC 1373 is one of the most compact and faint elliptical galaxies in the Fornax Cluster.[11] As NGC 1373 is a compact ellpitical galaxy, in the Fornax Cluster, it is expected to have older and more metal-rich populations of stars than similar compact elliptical galaxies of lower masses. It is thought that NGC 1373 originated as a more extended galaxy that transformed into a compact dwarf as it fell falling through the cluster.[12]

NGC 1373 appears to be interacting with the galaxy NGC 1374 and is separated from the galaxy by a distance of around 980,000 ly (0.3 Mpc).[10] This is evident as observations using the VLT Survey Telescope reveal the presence of a faint filament of matter connecting the two galaxies.[13]
