石申环形山(英語:Shi Shen)是位于月球背面北极圈附近的一座古老大撞击坑,约形成于39.2-38.5亿年前的酒海纪[1],其名称取中国战国时期魏国天文学家占星家石申(约公元前4世纪),1970年被国际天文学联合会正式接受。

描述

[编辑]

该陨坑东南靠近巨大的史瓦西环形山、西北偏北毗邻古老的南森环形山,其所在月表区有时通过月球摄动,可进入地球视野范围,但只能看到它的侧面,更多的细节无法看清[2]。该陨坑中心月面坐标75°47′N 104°08′E / 75.78°N 104.13°E / 75.78; 104.13,直径46.52公里[3],深约2.296公里[1]

石申环形山是一座古老、磨损的陨石坑,带有一圈已钝化及不规则的坑壁,其北侧内壁较为宽厚平缓,沿西北偏北坑沿覆盖了一座小撞击坑。它的坑壁最大高出周边地形1090米[1],内部容积约1693.65立方千米[1],坑底表面大体平整,但北部较粗糙坎坷。

按惯例,最靠近石申环形山的卫星坑在月图上以字母标注在该坑中心点的旁边。
