NGC 3861 is a large[2] barred spiral galaxy[3][1] with a ring-like structure[3] located about 310 million light-years away[4] in the constellation Leo.[5] It was discovered by astronomer John Herschel on March 23, 1827.[6] NGC 3861 is a member of the Leo Cluster and has a normal amount of neutral hydrogen (H I) and ionised hydrogen (H II).[2]
NGC 3861 is a low luminosity Type II Seyfert galaxy.[7] However, it is also classified as a LINER galaxy.[8][9]
