库代陨石坑(Couder)是位于月球背面巨大的科迪勒拉山脉内壁底部的一座小撞击坑,其名称取自法国天文学家安德烈·库代(1897年-1979年),1985年被国际天文学联合会正式接受。

描述

[编辑]

该陨坑西北偏西毗邻克拉马罗夫陨石坑、正东面靠近施吕特环形山,往南面稍远坐落了相对年轻的蒙德环形山,再往南则横亘了鲁克山脉及所环绕的东方海[1]。该陨坑中心月面坐标4°54′S 92°35′W / 4.90°S 92.58°W / -4.90; -92.58,直径18.56公里[2],深约1.736公里[3]

库代陨石坑外观呈圆杯状,东南部明显凸出,坑壁边缘完整清晰,内壁面较为平整,沿西侧内壁分布有反映了坑内近期地质活动的明亮滑坡带。陨坑坑壁最大高出周边区域760米[3],其中东侧壁顶较坑底落差达4000米[4],内部容积约为270立方千米[3]。坑内地表相对平坦,没有醒目的地貌结构。

尽管该陨坑位于月球背面,但有时通过月球摄动,可进入地球视野范围。

在1985年被国际天文学联合会正式命名前,该陨坑曾被称作卫星坑“蒙德 Z”(所谓的“卫星坑标记法”:以所靠近的主坑名+字母来命名)。
