        Bullialdus (61 km) at Mare Nubium, which is close to Mare Humorum.Bullialdus is an impact crater located on the west of Mare Nubium. To the south is Lubiniezky crater (44 km) in the form of broken frame, being flooded by lava. In the north-east of Bullialdus in photo, is K├Ânig (23 km), a smaller crater.
     because of relatively isolated location of Bullialdus we can highlight its shape well formed. Bullialdus has a large outer rim that is circular, but observers have noted is slight polygonal. The interior walls are terraced and contain many signs of landslides.
     Crater floor is somewhat convex, rounded up to the middle. When the sun is at a high angle, the central mountains appear brighter than the surroundings, and the white spots can be viewed on the crater floor.
     Two small craters, north of the crater,are: Bullialdus A and Bullialdus B.
