angle of crater的意思|示意

Streaming through a gap in the eastern wall of 45 kilometer wide Hesiodus crater, the low-angle sunlight produces a long sunrise ray playing along the otherwise Shadowed crater floor.

45千米宽的赫西俄德环形山，东壁一个缺口流泻出低角度的太阳光，在有阴影的环形山底形成长长的太阳光线(日出光？)

The angle of the sun, coming from the northwest or the left of the image, throws the gullies in the crater into sharp relief.

从西北边（即照片左边）直射过来的阳光将陨坑中的沟壑照得清清楚楚。

During the October 6, 2008 flyby of Mercury, MESSENGER's NAC captured a new view of the bright, radial ejecta rays of Kuiper crater that were previously imaged by Mariner 10 at a lower Sun Angle.

2008年10月6号飞越中的“信使号”用窄角镜头拍下了明亮呈放射状的柯伊伯陨石坑，“水手10号”曾在阳光斜射时拍摄这一区域。
