De Roy Q (Moon)

Satellite Feature of De Roy

Named after Felix De Roy - Belgian astronomer (1883-1942).

De Roy is a lunar impact crater on the far side , just behind the southwestern limb. This portion of the lunar surface is brought into view during favorable librations, allowing observation of this formation. However the crater is viewed from the side when watched from the Earth, and little detail can be seen. De Roy lies to the west of the crater Arrhenius, and east of the larger Boltzmann.
