万户环形山(Wan-Hoo)是位于月球背面赤道区的一座大型撞击坑,约形成于酒海纪代,以傳說中的十六世纪中国官员万户之名命名,1970年被国际天文联合会正式批准接受。

描述

[编辑]

该陨坑西北毗邻谢切诺夫环形山、北面坐落着瓦维洛夫环形山、巨大的赫茨普龙环壁平原位于它的东北、东侧则是埃文斯环形山、南面横亘着帕申环形山[1]。该陨坑的中心月面坐标9°58′S 138°55′W / 9.96°S 138.91°W / -9.96; -138.91,直径53.3公里[2],深度2.4公里[3]

该陨坑充塞着赫茨普龙环形山撞击时抛射的溅射物,外观已发生很大改变。环陨坑四壁覆盖着数座小陨坑,坑壁高出周边地形1140米,坑内容积约2200公里。碗形的坑底地势崎岖,地表散布着一些大小不同的陨石坑。大卫星坑埃文斯 Q连接在它的东南偏东,另一座年轻的小陨坑则附靠在它的东南侧壁上,同样,在它的西侧壁上也坐落着一座杯状的小陨坑。

该特征的名称来源万户,为一些现代文献(很多是西方文献)中描述的所谓“中国传统中记录的首位嘗試用火箭升空的人”。不过現存中國歷史資料中尚未發現关于万户飞天的确切记载。
