Pavlov is a large lunar crater (148 km)  in Ridge Section 139 on the lunar Far Side. Actually the largest crater, only partially shown in the upper right, is the crater Gagarin (265 km), named after the Russian Cosmonaut. A little note about Gagarin is that quite a bit of interest was shown by NASA and the Apollo imaging of that area. Located just to the north-northeast of Pavlov is the crater Levi-Civita and to the southeast is Jules Verne, out of frame and in Section 150.  Northwest of Levi-Civita and on the edge of our chart is the crater, Pirquet. The outer rim of Pavlov is somewhat worn and has been damaged in a few locations. There are outward bulges along the southern and eastern rim, and smaller bulges along the western side. Several small craters lie along the inner walls and the interior floor. Pavlov H is located along the east-southeastern edge of the floor. There is a small crater chain leading to the northwest of this satellite, culminating in a teardrop-shaped crater to the east of the midpoint of Pavlov. There are also small, cup-shaped craters along the southeastern and northwestern edges of the floor. Where it is not marked by tiny craters, the interior floor of Pavlov is relatively flat and level.
