|Bullialdus lunar crater. 17 July 2013, 22:00-22:28 LT|
The illuminated part of the floor of the crater is generally rough with many low rises. In the center of the crater is a formation of several peaks and rises that climb to over a kilometer in height. The sketch shows this prominent peak that comes out of the surrounding shadow simply because of its height.
Klima et al., (2013) showed how the central peak of Bullialdus Crater is significantly enhanced in hydroxyl relative to its surroundings. This is indicative that the peak originated from deep down below the crater as result of the immense impact pressure and heat.
Two smaller but notable craters lie just to the south of the main crater. Bullialdus A lies just to the south-west of Bullialdus, within its ramparts. To the south of Bullialdus A is the slightly smaller Bullialdus B.To the Southwest is the conspicuous but smaller lunar crater Konig. Its shadow suggests a tapering side wall towards the northwest.
