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-shaped due to foreshortening.

The northern rim of this crater intersects the smaller lava-flooded Russell crater to the north, and there is now a wide gap between the two formations. Attached to the southeast rim is the remains of another lava-flooded formation, Eddington crater. Further to the southwest is Balboa crater, near the lunar limb.

The rim of Struve crater is heavily worn and irregular, with several gaps connecting to the surrounding maria. It resembles little more than a circular mountain range, climbing to a maximum height of 1.7 km. There are several small impact crater sites within the wall, most notably in the southeast part of the crater. The Struve G crater overlaps the inner part of the western rim, and just to the north of this crater is a gap in the wall that connects to the Oceanus Procellarum between the rims of Russell and Eddington craters. The Lunar maria (singular: mare, pronounced MAH-ray) are large, dark, basaltic plains on Earths Moon, formed by ancient basaltic flood eruptions caused by extremely large meteoroid impacts. ...

By convention these features are identified on Lunar maps by placing the letter on the side of the crater mid-point that is closest to Struve crater.
