Purkyně D (Moon)

Satellite Feature of Purkyně

Named after Jan Evangelista Purkyně - Czechoslovakian doctor, physiologist (1787-1869).

Purkyně is a lunar impact crater that lies just beyond the eastern limb , on the far side from the Earth. When conditions of libration and sunlight allow, this crater can be viewed from the Earth, although it is seen from a very low angle and not much detail can be seen. This crater lies just to the west of the larger crater Wyld, and to the north-northwest of the even bigger Hirayama. To the west and northwest is the Mare Smythii. (wikipedia entry)
