Pikel'ner Y (Moon)

Satellite Feature of Pikel'ner

Named after Solomon Borisovich Pikel'ner - Soviet astronomer, cosmologist (1921-1975).

Pikel'ner is an impact crater. It lies to the southeast of the larger crater Van der Waals, and to the north of the Vallis Planck cleft. Pikel'ner overlies more than half of the satellite crater Pikel'ner Y to the north. Almost contacting the southwestern outer rim is a larger concentric crater formation with the smaller crater of the pair, Pikel'ner S, along the northern edge of the pair. (wikipedia entry)
