恰普雷金环形山(Chaplygin)是月球背面赤道区附近一座古老的大撞击坑,约形成于酒海纪[1],其名称取自苏联数学家机械工程师谢尔盖·阿列克谢耶维奇·恰普雷金(1869年-1942年),1970年被国际天文学联合会批准接受。

该陨坑位于巨大的环壁平原-门捷列夫环形山东南,东北和西南分别毗邻谢里曼环形山马可尼环形山。恰普雷金环形山大小类似于月球正面阿尔巴塔尼环形山,其中心月面坐标5°46′N 150°14′W / 5.76°N 150.24°W / 5.76; -150.24,直径123.39公里[2]。 深度2.918公里[3]

该环形山轮廓外观大致呈圆形,但各边缘并不均匀。环内侧坡大部为阶地状地貌,但该结构在南侧被打乱。整体边缘只受到所环绕撞击坑的轻度侵蚀,只有东南侧切入了卫星坑恰普雷金 K;陨坑壁高出周边地形1610米,内部容积约16122.55立方千米[1]。坑内地表较周边崎岖的地形更平坦,但没有熔岩射纹系统,中心点附近坐落着一座中央峰,四周散布着一些细小的月坑。

按惯例,最靠近恰普雷金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。

恰普雷金 月面坐标 直径, 公里
K 7°41′S 151°22′E / 7.68°S 151.36°E / -7.68; 151.36 (Chaplygin K) 9.55
Q 7°38′S 147°55′E / 7.64°S 147.91°E / -7.64; 147.91 (Chaplygin Q) 12.69
Y 2°43′S 149°38′E / 2.71°S 149.64°E / -2.71; 149.64 (Chaplygin Y) 27.53
