Pictet (crater)
Pictet is a lunar impact crater located just to the east of the larger and more prominent impact crater Tycho. The high-albedo rays and ejecta from Tycho lie across Pictet and spread far to the east and in other directions. Pictet is older than Tycho and is somewhat worn by past impacts. The slightly smaller crater Pictet A intrudes slightly into the southwest rim. The larger crater Pictet E is nearly joined to the north rim. To the east is Saussure, and to the northeast is the larger, worn formation Orontius.

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 Pictet.
