Eijkman (crater) : ウィキペディア英語版 | 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. The inner walls display some minor terracing along the northwestern edge. Near the midpoint of the crater interior floor is a horseshoe-shaped central peak formation, with the open end pointing towards the south. ==Satellite craters== By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Eijkman.
