The orientation of the planet's orbit is changing continuously.
该行星轨道的方向不断变化。
Such a planet would rotate in a different plane in orientation to our current planet orbits, and probably formed in a wide-binary orbit.
这样一颗行星旋转的平面与我们的不同,并且有可能形成远距双星的轨道。
In fact, this is what almost happens, except that the nodes of the lunar orbit are gradually shifting their orientation in space.
实际上差不多就是这样发生的,只不过月球轨道交点的空间方位有渐移运动。
