Burnham 7.30 E 13.90 S A 24-km crater with broken wall.

Albategnius 4.30 E 11.70 S A prominent ring mountain with central peak and flatten floor, 114 km in diameter. Its inner wall is heavily eroded with landslides, valleys and impact craters including Klein (44 km). The immediate north of Albategnius is Hipparchus.


A vast walled plain, 138 km in diameter. The eastern wall is cut by a pair of deep clefts, which is part of the Imbrium Sculture. The western wall is fairly disintegrated, with a gap opened to Rima Reaumur (length 30 km). The flooded floor of Hipparchus contains small hills, ghost craters and Horrocks. See also Image
