博斯科维奇陨石坑1645

描述

该陨坑西北靠近曼尼里乌斯陨石坑、东北毗邻更大的尤利乌斯·凯撒环形山，较小的斯伯奇莱克陨石坑位于它的东南，而它的南面则横亘了阿里亚代乌斯月溪。该陨坑中心月面坐标为9.71°N 11.01°E / 9.71; 11.01，直径41.53公里，深约2.22公里。

由于存续时期悠长，博斯科维奇陨石坑几乎已被后续的撞击完全损毁，残壁最大高出周边地形1040米，内部容积约1303.15立方千米。除西半部外，坑内地表较为平坦，其表面反照率较周边背景地形明显更低，在该区域中形成一处突出的暗斑。坑内地表已被从西北裂口处涌入的月海熔岩所淹没，平坦的表面上只散布有一些细小的撞击坑。

该陨坑内部的施罗特亮度等级为1½°，是月球上最幽暗的地貌特征之一。坑底表面分布有一条延伸40公里，被称作“博斯科维奇月溪”的叉枝形沟壑。

卫星坑

按惯例，最靠近博斯科维奇陨石坑的卫星坑将通过在月图上其中心点旁标注的字母来识别它们。

Boscovich is a lunar impact crater that has been almost completely eroded away by subsequent impacts. It is located west-northwest of the crater Julius Caesar, and south-southeast of the prominent Manilius. T. W. Webb described it as a very dark enclosure. It is an irregular formation with a low outer wall. The crater floor has a low albedo, and the dark hue makes it relatively easy to recognize. The surface is crossed by the rille system designated Rimae Boscovich that extends for a diameter of 32 kilometres. Two of these rilles lie at right angles to each other.

This crater is named after Croatian physicist Roger Joseph Boscovich (1711-1787). His name was introduced into lunar nomenclature during the 18th century by German astronomer Johann H. Schröter. Its designation was formally adopted by the International Astronomical Union in 1935.

Satellite craters

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Boscovich.
