Tags: Crater.
Pannekoek is a lunar impact crater that is situated on the far side of the Moon and cannot be seen directly from the Earth. The crater lies along the northern edge of the slightly larger Dellinger and their common border forms an area of uneven terrain. Due north of Pannekoek is the huge walled plain Mendeleev.This is a worn and eroded crater although the perimeter of the rim is still visible. The southern part of the interior floor is jumbled and irregular.
