弗勒利希环形山(Froelich)是位于月球背面北极附近一座古老的大撞击坑,约形成于39.2-38.5亿年前的酒海纪[1],其名称取自美国航空航天工程师杰克·爱德华·弗勒利希(1921年-1967年),1970年被国际天文学联合会正式接受。

描述

[编辑]

该陨坑西侧是更古老的潘索环形山、北面靠近略小的洛夫莱斯环形山,巨大的布利安生环形山坐落在它的东南偏东,南面横亘着稍大的梅里尔环形山,而它的东侧则斜插着绵延173公里的西尔维斯特链坑[2]。该陨坑中心月面坐标80°00′N 111°38′W / 80.00°N 111.63°W / 80.00; -111.63,直径56.73公里[3],深约2.439公里[1]

弗勒利希环形山外观接近圆状,坑壁已明显磨损,东北侧连接了一座醒目的杯状坑,沿内壁仍残留有一些阶坡状结构痕迹。它的坑壁最大高出周边地形表面1180米[1],内部容积约有2678.46立方千米[1]。坑内地表相对平坦,中心点附近坐落了一座小圆顶丘,并从它的西北延伸着一道弧形山脊。

按惯例,最靠近弗勒利希环形山的卫星坑将在月图上以字母标注在它的中心点旁边。
