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]
