NGC 7713 is a barred spiral galaxy with extensive Hubble-type SBcd star-forming regions that is located in the constellation Sculptor in the southern sky. It is estimated to be 31 million light-years from the Milky Way and about 40,000 light-years in diameter. ^{[2] [3] [4]} It was discovered by John Herschel on October 4, 1836. ^[5]

Supernova

One supernova has been observed in NGC 7713: SN 1982L (type II, mag. 16) was discovered by Marina Wischnjewsky on 21 July 1982. ^{[6] [7]}
