NGC 4074

NGC 4074 is a peculiar[2][3] lenticular galaxy located 310 million light-years away[3] in the constellation Coma Berenices.[4] It was discovered by astronomer William Herschel on April 27, 1785[5] and is a member of the NGC 4065 Group.[6][7][8][9][10]

NGC 4074 is classified as a type 2 Seyfert galaxy.[3][11][2][12] It was first identified as a Seyfert in 1978.[13]
