Geological Chronicle
Perched near the northern limb of the Moon, north of Philolaus and northwest of Anaxagoras, Mouchez is the eroded remnant of an ancient impact crater spanning 82.78 kilometers across. The feature honors the French astronomer Ernest Amédée Barthélemy Mouchez.
Erosion has erased almost the entire eastern rim of the crater, leaving a heavily worn arc curving clockwise from the south to the north-northeast. Near the southern end of this surviving wall sits the small crater Mouchez C, while the interior forms a level plain marked by tiny impacts and the small crater Mouchez B.
Beyond the primary structure, a smaller replica of Mouchez forms a curving ridge attached to the southern outer wall. Along the northern exterior lies the flooded crater Mouchez A, which preserves a nearly intact rim interrupted only by gaps along its northwestern side.
