Fra Mauro B (Moon)

Satellite Feature of Fra Mauro

Italian geographer (unkn-1459).

Fra Mauro is the worn remnant of a walled lunar plain. It is part of the surrounding Fra Mauro formation, being located to the northeast of Mare Cognitum and southeast of Mare Insularum. Attached to the southern rim are the co-joined craters Bonpland and Parry, which intrude into the formation forming inward-bulging walls. The surviving rim is heavily worn, with incisions from past impacts and openings in the north and east walls. (wikipedia entry)
