Vesalius (Moon)

Named after Andreas Vesalius - Belgian doctor (1514-1564).

Vesalius is a lunar impact crater that lies on the far side , less than 100 kilometers south of the lunar equator. Just to the northwest is the slightly smaller crater Buisson. Farther to the west-southwest lies the prominent crater Einthoven. The outer rim is generally circular but somewhat irregular. (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.
