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

[edit]

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]
