Chaplygin (crater)
 Chaplygin is a large lunar impact crater that lies on the far side of the Moon. It is located to the southeast of the huge walled plain Mendeleev about mid-way between the craters Schliemann to the northeast and Marconi to the southwest. It is about the same size as Albategnius on the near side.The rim of this crater is roughly circular but with an uneven edge. The inner wall is terraced around much of the circumference but this structure is somewhat disrupted along the southern side.
