NGC 3861 is a large[2] barred spiral galaxy[3][4] with a ring-like structure[3] located about 310 million light-years away[5] in the constellation Leo.[6] It was discovered by astronomer John Herschel on March 23, 1827.[7] 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.[8] However, it is also classified as a LINER galaxy.[9][10]
On March 7, 2014, a type Ia supernova designated as SN 2014aa was discovered in NGC 3861.[11][12][13]
