Oblique view of Kiess and Widmannstätten from Apollo 12

Widmannstätten is a lunar impact crater in the southern part of the Mare Smythii, near the eastern limb of the Moon. The rim of this crater has a wide gap along the western side, where it is joined to the larger Kiess. There is also a gap in the northern rim where the crater floor is joined to the adjacent lunar mare. The dark interior floor of this formation has been flooded by lava, leaving a level interior surface and a shallow surviving rim.

Both Kiess and Widmannstätten have fractured floors.[2]

The craters Kiess and Widmannstätten were referred to as Wright Brothers, such as by the crew of Apollo 17,[3] prior to being officially named by the IAU in 1973.[4]
