NGC 3916 is a spiral galaxy in the constellation of Ursa Major. Its velocity with respect to the cosmic microwave background is 5,922±12 km/s, which corresponds to a Hubble distance of 284.9 ± 20.0 Mly (87.34 ± 6.12 Mpc).[1] It was discovered by German-British astronomer William Herschel on 14 April 1789.[2][3]
NGC 3916 is a LINER galaxy, i.e. a galaxy whose nucleus has an emission spectrum characterized by broad lines of weakly ionized atoms.[4][5] NGC 3916 is also a radio galaxy, i.e. it has giant regions of radio emission extending well beyond its visible structure.[6][5]
Galaxy group
NGC 3916 belongs to a small galaxy group known as LDC 846.[7][8] The other two galaxies in the group are NGC 3921 and NGC 3977.[7][8]
Supernova
One supernova has been observed in NGC 3916:
- SN 1974D (type unknown, mag. 15.5) was discovered by Miklós Lovas on 20 March 1974.[9][10]
