Geological Chronicle
Sinus Successus lies along the eastern edge of Mare Fecunditatis, forming an outward bulge that acts as a bay. The feature spans 126.65 kilometers in diameter, centered at selenographic coordinates 1.12° N, 58.52° E.
Along the eastern edge of the bay lies the flooded crater Condon, while the crater Webb forms its southern end. The bay contains no other features of significance.
The terrain just to the northwest of Sinus Successus served as the landing site for the Soviet Luna 18 and Luna 20 probes.
