Struve (Moon)

Named after Otto Wilhelm von Struve - German-born Russian astronomer (1819-1905) and Otto Struve - American astronomer (1897-1963) and Friedrich Georg Wilhelm von Struve - German-born Russian astronomer (1793-1864).

Struve is the lava-flooded remains of a lunar impact crater. It is located near the western extreme of the Oceanus Procellarum, close to the western lunar limb. As a consequence, even though it is roughly circular in outline, it appears oval due to foreshortening. The northern rim of this crater intersects the smaller lava-flooded crater Russell to the north, and there is now a wide gap between the two formations. (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.
