Davy is a small lunar impact crater that is located on the eastern edge of the Mare Nubium.

The perimeter is somewhat polygonal in shape, especially in the western half, and the southeast rim has been overlain by Davy A.

[3] This linear string of 23 tiny craters runs from the midpoint of Davy Y towards the walled basin Ptolemaeus, following a slightly curving course to the east-northeast.

The most likely cause is believed to be a single body that broke apart prior to impact due to tidal effects.

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