Several satellite craters in the vicinity have since been given names by the IAU. Nearly attached to the north-northeastern rim of Gilbert are Weierstrass (Gilbert N) and Van Vleck (Gilbert M) craters, two somewhat similar formations. In the northeastern part of Gilbert's interior floor is the small, bowl-shaped Geissler crater (Gilbert D).
The Gilbert crater is a somewhat degraded walled plain, with an outer rim that has been somewhat reshaped by nearby impacts. The southern rim has almost completely disintegrated, and forms a rolling surface that flows toward the south as an extended depression. The crater pair of Weierstrass and Van Vleck have formed an indented rim along the northeast face, while the northwest rim is overlaid by 'Gilbert S'. The interior floor is relatively level with some low ridges running down the center toward the southern end.
Satellite craters
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 Gilbert crater.
