Marci (Moon)

Named after Jan Marek Marci von Kronland - Czechoslovakian physicist (1595-1667).

Marci is a small, mostly unremarkable lunar crater on the far side. It is located about one crater diameter to the west of the prominent crater Jackson. To the northwest is the larger crater Fitzgerald. This is a roughly circular, bowl-shaped feature with slight outward bulges in the rim to the north and south. (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.
