NGC 7038 is an intermediate spiral galaxy located about 210 million light-years away in the constellation of Indus.[2][3] Astronomer John Herschel discovered NGC 7038 on September 30, 1834.[4]
NGC 7038 along with NGC 7014 are the brightest members of Abell 3742.[5][6] Abell 3742 is located near the center of the Pavo–Indus Supercluster.[7]
