is a small
Lunar Impact Crater that is located in the southern part of the
Oceanus Procellarum , to the northeast of
Gassendi Crater . The Herigonius crater is roughly circular, with an inward bulge and narrower inner wall along the northeast. In the interior of the sloping inner walls is a floor about half the diameter of the crater.
About 60
Kilometer s to the west of Herigonius crater is a sinuous
Rille designated ''Rima Herigonius''. This cleft is about 100 kilometers in length and runs generally in a north-south direction, while curving to the east at the north end.
By convention these features are identified on lunar maps by placing the letter on the side of the crater mid-point that is closest to Herigonius crater.
