Dobrovolʹskiy (crater) explained

Coordinates:-12.83°N 129.68°W
Depth:[1]
Colong:231
Eponym:Georgiy T. Dobrovolskiy

Dobrovolskiy is a small lunar impact crater on the Moon's far side. The northwest part of its rim is intruded upon by the somewhat larger crater Shirakatsi, and the outer rampart of that feature covers most of the interior floor of Dobrovolskiy. Very little of the original floor now survives, with a small section near the southern inner wall. The remainder of the crater rim is somewhat circular and only mildly worn.[2]

To the north the southern rim of the much larger crater Perepelkin is intruded upon by Shirakatsi, and the three form a brief, curving crater chain. To the southeast of Dobrovolskiy is the crater Volkov.

In 1973, the crater was named after cosmonaut Georgiy T. Dobrovolskiy, who died during the Soyuz 11 mission.[3]

Satellite craters

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Dobrovolskiy.
