Although the Earth and the Moon always cast long shadows, they rarely shade each other thanks to the Moon's orbital tilt.

尽管地球和月球总是投下长长的阴影，但由于月球的轨道倾斜，它们很少相互遮蔽。

Throughout the year, the Moon's orbital tilt remains fixed with respect to the stars, meaning that it changes with respect to the Sun.

在一年中，月球轨道的倾斜相对于恒星保持固定，这意味着它相对于太阳发生变化。
