Einthoven is a lunar impact crater that is located on the far side of the Moon. It is located beyond the region of the surface that is sometimes brought into view due to libration, and so can not be viewed from the Earth. Einthoven is located to the northeast of the huge walled plain Pasteur.

This is a circular crater with some minor terrace structure along the inner rim. The satellite crater Einthoven X is attached to the northwestern rim, and is partly overlaid by Einthoven. The hummocky interior floor is marked only by a small crater in the eastern half and a few tiny craterlets.

Prior to formal naming by the IAU in 1970,[1] Einthoven was called Crater 273.[2]

Satellite craters[edit]

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