Lubiniezky (Moon)

Named after Stanislaus Lubiniezky - Polish astronomer (1623-1675).

Lubiniezky is a lava-flooded lunar crater on the northwest edge of Mare Nubium. This feature is most readily located by finding the prominent crater Bullialdus to the southeast. The floor has been resurfaced by basaltic lava, which most likely entered from the surrounding mare through the gap in the southeast wall. The surviving rim forms a curved, worn rise around the flat and featureless inner floor. (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.
