Johannes Campanus Novariensis.
Version des Eléments d'Euclide |
Campanus
is a lunar impact crater that is located on the southwestern edge of
Mare Nubium. It forms a crater pair with Mercator crater just to the
southeast. Along the southern rampart of Campanus is the small lunar
mare named Palus Epidemiarum. To the southwest is the small Dunthorne
crater.
The rim of Campanus is roughly circular, with an outward bulge along
the western rim and an inward bulge to the north-northwest. The outer
wall has not been significantly eroded, although it has a low
saddle-point along the south. The interior floor has been resurfaced by
basaltic-lava, leaving only a small central peak projecting above the
surface. The floor has the same low albedo as the nearby mare, giving
it a dark appearance. It is marked by a pair of tiny craterlets near
the northeast and northwest interior walls. A slender rille crosses the
crater floor from north to south, passing to the east of the central
peak.
