Tags: Crater.
Fracastorius is the lava-flooded remnant of an ancient lunar impact crater located at the southern edge of Mare Nectaris. To the northwest of this formation lies the crater Beaumont while to the northeast is Rosse.The northern wall of this crater is missing with only mounds appearing in the lunar mare to mark the outline. The lava that formed Mare Nectaris also invaded this crater so the structure now forms a bay-like extension.
