Yakovkin (Moon)

Named after A. A. Yakovkin - Soviet astronomer (1887-1974).

Yakovkin is a lunar crater that lies very near the southwest limb. It is located to the northwest of the crater Pingré, and was designated Pingré H before it was named by the IAU. The proximity of this crater to the limb hinders observation from the Earth, and gives it a foreshortened appearance. The uneven rim of this crater has a polygonal shape, rather than forming a simple circle. (wikipedia entry)

A crater is a circular depression likely created by an impact event. On the Moon they are named after deceased scientists, polar explorers, astronauts or cosmonauts.
