Stadius crater is one which can barely be seen because it is almost completely flooded, and therefore very difficult to distinguish its edge. Crater shape is circular, and its floor is riddled with many small impacts, some forming rows of craters in formation, from south to north.
Stadius, with a diameter of 69 km, is considered a ghost crater, and the hardly distinguishable edge is due to the fact that in the past was flooded by basaltic lava. The floor is crossed by many small craters and on the west there's a chain of small craters reaching the Imbrium basin, being named after Stadius. Stadius has so many satellite craters framing almost the whole alphabet, from Stadius A to Stadius W.
The position of Stadius, is southwest of Eratosthenes (58 km) and east of Copernicus (93 km).
The name of this crater is from Johannes Stadius or Estadius, (1 May 1527-17 June 1579). He was a flamand astronomer, astrologer and mathematician.
