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
[edit]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]
IC 5332 Group
[edit]According to A.M. Garcia, NGC 7713 is a member of the IC 5332 galaxy group (also known as LGG 478). This small group has three galaxies, including IC 5332 and PGC 72525.[8]
