Virtanen is a lunar crater that is located to the northeast of the larger crater Sharonov and to the east of Anderson. Virtanen lies on the far side of the Moon and cannot be viewed directly from the Earth.This crater has a nearly circular rim with a relatively narrow inner wall and a small rise near the interior midpoint. A small crater impact near the eastern rim lies at the focus of a small ray system that covers much of Virtanen and its surroundings.
