Fracastorius G (Moon)

Satellite Feature of Fracastorius

Named after Fracastoro, Girolamo Fracastorius - Italian doctor, astronomer (1483-1553).

To the northwest of this formation lies the crater Beaumont, while to the northeast is Rosse. The lava that formed Mare Nectaris also invaded this crater, so the structure now forms a bay-like extension. The remainder of the rim is heavily worn and covered in lesser impact craters, leaving little of the original rim intact. (wikipedia entry)
