皮亚齐环形山(Piazzi)是位于月球正面南半部一座古老的大陨坑残迹,约形成于45.5-39.2亿年前的前酒海纪[1],其名称取自十八世纪意大利天文学家神父朱塞佩·皮亚齐(1746年-1826年),1935年被国际天文学联合会批准接受。

描述

[编辑]

该陨坑西北与巨大的环壁平原-拉格朗日环形山相接壤、东南偏东毗邻拉克鲁克斯陨石坑施卡德环形山坐落在它的东南,而往南约300公里则是因吉拉米环形山[2]。该陨坑中心月面坐标36°10′S 68°01′W / 36.16°S 68.01°W / -36.16; -68.01,直径102.6公里[3],深度1.62公里[4]

与拉格朗日环形山一样,皮亚齐环形山也已被西北方东方海撞击盆地形成时所喷出的溅射物严重侵蚀,这些物质在二座陨坑的表面形成了呈放射状分布的峡谷和山脊,使皮亚齐环形山几乎成为一处边沿难辨的洼地。陨坑的外侧壁形状不规则,且已磨损,坑底北部数处地表已被黝黑的玄武岩熔岩淹没和抹平,中心处是一座已被夷平的巨大中央峰残迹,凹凸不平的坑底上还散布有一些小陨坑。

按惯例,最靠近皮亚齐环形山的卫星坑将在月图上以字母标注在该坑的中心点旁。
