NGC 7816 is a spiral galaxy located about 215 million light-years away [2] in the constellation of Pisces. [3] It was discovered by astronomer William Herschel on September 26, 1785. [4]
One supernovae has been observed in NGC 7816: SN 2017gww ( type II, mag. 17.9) [5]
Pair with NGC 7818
NGC 7816 is listed as being in pair with the galaxy NGC 7818. [4] [6] NGC 7818 is also listed as being a disturbed member of the pair. [4] [7] However, due to the large difference in their recessional velocities, the two galaxies are not a true pair but an optical double. [4]
