IC 3370 is an elliptical galaxy located in the constellation of Centaurus. It is located 156 million light-years from Earth.[1] It was discovered by American astronomer Lewis Swift on 30 January 1898.[2][3] According to the SIMBAD database, IC 3370 is said to be a LINER galaxy but also a Seyfert type II galaxy.[4] The luminosity of the galaxy is estimated to have a B magnitude of -22.3, similar to other elliptical galaxies.[5]
IC 3370 is classified as an E2-E3 elliptical galaxy with a bright nucleus.[6] The galaxy has a box-shaped appearance similar to LEDA 74886,[7][8] although some studies classified it as a peculiar lenticular galaxy (S0pec).[6] It has isophotal twisting in its galactic bulge to a significant extent between 0 and 70 arcseconds, indicating the galaxy might have gone through a tidal-encounter or a galaxy merger.[9] There are also dust patches covering most of the nuclear regions in the galaxy with signatures of X-ray isotopes and cylindrical rotation.[10][7][11] The inner disk of the galaxy is shown to be rotating at speeds of 100 km s−1.[8] It has a dust lane running through the galaxy's central region.[12]
