. About three crater diameters to the west is the prominent
Tsiolkovskiy. To the north-northeast of Pirquet is
Denning.
The rim and interior of Pirquet are marked by a number of small craterlets. A small crater is protruding into the inner wall along the south-southeastern side. This crater is slightly elongated along the east–west direction, making it appear slightly oval.
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 Pirquet.
