LO-IV-113H The 15-km diameter crater straddling Davy’s southeast rim is Davy A. A part of 7-km Davy B can be seen in the upper left. The ridge that runs towards it is a small part of the rim of 70-km diameter Davy Y, the lettered crater containing the famous Catena Davy. The little grouping of craters in the upper right (which fall on the floor of Davy Y) are regarded as part of that Catena Davy, although they are not well aligned with the others.

Nomenclature
- Named for Sir Humphry Davy, 1st Baronet, FRS (17 December 1778 – 29 May 1829), a British chemist and physicist. Berzelius called Davy's 1806 Bakerian Lecture "On some Chemical Agencies of Electricity" "one of the best memoirs which has ever enriched the theory of chemistry." This paper was central to any chemical affinity theory in the first half of the ninteenth century.
- In the North American Atlas, Dinsmore Alter used the unofficial name "Rectangle" to designate a "prominent, but unnamed, feature" which seems to correspond to the IAU's Davy Y.
