NGC 3860 is a spiral galaxy[3] located about 340 million light-years away[4] in the constellation Leo.[5] NGC 3860 was discovered by astronomer William Herschel on April 27, 1785.[6] The galaxy is a member of the Leo Cluster[7][8] and is a low-luminosity AGN (LLAGN).[9][10] Gavazzi et al. however classified NGC 3860 as a strong AGN which may have been triggered by a supermassive black hole in the center of the galaxy.[11]
