Tags: Crater.
Firsov is a lunar crater on the far side of the Moon. It is located to due south of the crater Lobachevskiy and to the northwest of Abul Wáfa. The circular rim of this crater has a small outward bulge along the southern edge and smaller bulges along the western side. The inner walls have slumped to form talus piles along the base. The low-albedo interior floor is nearly level and featureless.
