| Eponym | Geminiano Montanari |
Montanari is a lunar crater. It is located to the west-southwest of the prominent Tycho crater, and is attached to the southern rim of the Wilhelm walled plain. Along the northwest side is the Lagalla crater remnant, and just to the south is the large Longomontanus walled plain.
The rim of Montanari has been so deeply eroded by impacts that it is now little more than an irregular border around the interior floor. These impacts have distorted the shape of the crater, and have nearly obliterated the southern rim. Ejecta from Longomontanus overlays part of the southern floor. The satellite crater 'Montanari D' is laid across the western rim, and covers part of the interior floor. The northern part of the floor is more regular and featureless than in the south.
Satellite craters
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 Montanari crater.
