Pomortsev is a small lunar crater that is located in the eastern part of the Moon's near side. It lies on the eastern edge of Mare Spumans, to the southwest of the crater Dubyago. This formation was previously designated Dubyago P before being given a name by the IAU. One crater diameter to the north is the smaller Stewart. The nearly featureless interior of this crater has been resurfaced by basaltic lava, leaving a dark floor with an albedo that nearly matches the lunar mare to the west. The crater it roughly circular, with slight outward bulges to the north and northeast. The inner wall is wider along the southern half of the rim, and at its narrowest along the northwestern rim where the crater makes contact with Mare Spumans. ==References== * * * * * * * * * * * * 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Pomortsev (crater)」の詳細全文を読む スポンサード リンク
