NGC 3840 is a spiral galaxy[2] located about 320 million light-years away[3] in the constellation Leo.[4] The galaxy was discovered by astronomer Heinrich d'Arrest on May 8, 1864.[5] NGC 3840 is a member of the Leo Cluster.[6][7][8] The galaxy is rich in neutral atomic hydrogen (H I) and is not interacting with its environment.[9]
NGC 3840 is likely to be a low-luminosity AGN (LLAGN).[10]
