Walther (crater) : ウィキペディア英語版 | Walther (crater)
:''Not to be confused with Walter, a tiny crater near Diophantus. Walther is an ancient lunar impact crater located in the southern highland region of the Moon. It is joined along the western rim to the crater Deslandres. To the northeast is Aliacensis, and joined to the southeast rim is the irregular Nonius. ==Description==
The rim of Walther is complex, heavily eroded and incised by lesser impacts. The wall retains a generally circular form, but many of its features have been worn away and there is a slight protruding bulge in the western rim. The floor has been resurfaced after the original impact, leaving the southwestern half relatively smooth. In the northwest quadrant is an offset central peak that has been worn and impacted by several small craters.
