Hayn J (Moon)

Satellite Feature of Hayn

Named after Friedrich Karl Hayn - German astronomer (1863-1928).

Hayn is a lunar impact crater that lies next to the northeast limb. This location restricts the amount of detail that can be viewed from the Earth, as the western inner side is permanently hidden from sight. Observation of this crater can also be affected by libration, which can completely hide this crater from sight. This crater lies across the northwestern rim of the walled plain Bel'kovich, to the north of the Mare Humboldtianum. (wikipedia entry)
