NGC 3877 is a spiral galaxy in the northern constellation of Ursa Major,[1] to the south of the magnitude 3.7 star Chi Ursae Majoris.[4][5] It was discovered by the German-British astronomer William Herschel on February 5, 1788.[4] This galaxy has a visual magnitude of 11.2 and spans an angular size of 5.3′ × 1.2′.[1] It lies at a distance of 50.5 ± 4.2 million light-years (15.5 ± 1.3 Mpc).[3]

One supernova has been observed in NGC 3877: SN 1998S (Type IIn, mag. 15.2) was discovered by the BAO Supernova Survey on 3 March 1998.[6][7][4]

NGC 3877 is a member of the M109 Group, a group of galaxies located in the constellation Ursa Major that may contain over 50 galaxies. The brightest galaxy in the group is the spiral galaxy M109.[8][9][10]
