伯德环形山(Byrd)是位于月球正面北极区的一座大撞击坑,约形成于45.5-39.2亿年前的前酒海纪[1],其名称取美国飞行员极地探险家理查·伯德(1888年-1957年),1964年被国际天文学联合会正式批准接受。

描述

伯德环形山的周边,月球轨道器4号拍摄。
伯德环形山周边区域地形图,来自月球勘测轨道飞行器光学雷达数据。

该陨坑西北毗邻弗洛里环形山、北面贴近皮里环形山、小陨坑厄尔兰格菲比格位于它的东北、它的西南坑壁上则横跨了焦亚陨石坑[2]

该陨坑中心月面坐标85°26′N 10°04′E / 85.43°N 10.07°E / 85.43; 10.07,直径97.49公里[3],深度约2.85公里[1]

伯德环形山坑壁已被磨损和侵蚀,部分边缘因相邻陨坑的撞击切入而变形,使得坑底南北向更长。沿陨坑西侧壁分布有一处开放的裂口,而南侧壁则形似月表上一道低矮的山脊。伯德环形山坑壁最大高出周边地形1470米[1],坑内容积约9356立方千米[1]。在最初撞击发生后不久,该陨坑内部就被熔岩流覆盖,形成一块平坦,仅显示有一些微小浅坑的坑底,没有中央峰,也没有较大的山脊。

按惯例,最靠近伯德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。
