Eötvös (Moon)

Named after Lóránt (English - Roland) von Eötvös - Hungarian physicist (1848-1919).

Eötvös is the remains of a lunar crater on the far side. It lies to the north-northwest of the walled plain Roche, and east-southeast of the equally ruined Bolyai. Only the northwestern section of the crater's rim survives, the remainder now forming a battered, uneven circular rise. The rim is nearly non-existent along the southeast where it joins an uneven plain reaching the rim of Roche. (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.
