Named after William Whewell - British philosopher (1794-1866).
Whewell is a lunar impact crater that lies on a stretch of lava-resurfaced terrain to the west of Mare Tranquillitatis. It is located to the east of the disintegrated crater Tempel and north-northwest of D'Arrest. To the east is Cayley, a slightly larger but very similar formation. To the North lies the Rima Ariadaeus, which is a linear rille that is 300 kilometers long and was formed when a section 's crust sank down between two parallel fault lines, producing a graben.
