          Catharina (100 km), is a Moon impact crater located in the mountainous south, and is located west between Rupes Altai wich is a steep slope,and Mare Nectaris at east. To the northwest is the Tacitus crater. In the north it borders Cyrillus and Teophillus. Catharina form a prominent group along with the two craters, which are framed by Rupes Altai. There is a difference between the ages of the three craters, their age increasing from north to south.
Catharina's edge is very worn and irregular, especially in the north wall where is Catharina P crater (46 km). Northeast wall is deeply affected by several small craters. The floor is relatively flat with a curved ridge formed by Catharina P.
            Eponymous of this crater is Saint Catherine of Alexandria, also known Holy Great Martyr Catherine, who is a Christian saint and martyr, and is believed to have lived in the early fourth century.
          Geber crater is located halfway between Almanon crater at northeast  and the pair craters Abenezra and Azophi on southwest. Further to the southeast is Sacrobosco. Geber is 45 kilometers in diameter and 3510 meters deep.
The name of the crater comes from Abu Muhammad Jabir ibn AflaŠł• or Geber / Gebir (1100-1150), the Muslim astronomer and mathematician of Seville.
