Wróblewski (Moon)

Named after Sigmund von Wróblewski - Polish physicist (1845-1888).

Wróblewski is a small lunar crater that lies just to the southeast of the huge walled plain Gagarin. The crater Raspletin lies along the rim of Gagarin just to the northwest of Wroblewski. To the south-southeast is Sierpinski. As with many lunar craters of this size, Wroblewski is roughly circular and bowl-shaped. (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.
