Eijkman (crater)
 Eijkman is a lunar impact crater that is located on the far side of the Moon's southern hemisphere. It lies about a half crater diameter to the southeast of the larger crater Lemaître. To the south-southwest is the crater Crommelin and to the northeast is Fizeau.The rim of this crater is well-defined and has not been significantly worn down by impacts. Nevertheless there are a few tiny craterlets along the edge and a small craterlet along the northern inner wall.
