| 1. | Almost parallel to the orbital plane
自转轴几乎和公转平面平行 |
| 2. | Almost perpendicular to the orbital plane
几乎和公转平面垂直 |
| 3. | As a result , uranus seems to be rolling on the orbital plane
，换句话说，天王星就好像是在公转轨道上滚动著。 |
| 4. | Instantaneous orbital plane
瞬时轨道面 |
| 5. | First , we know that the planets all orbit close to the earth ' s orbital plane , the ecliptic
首先，我们知道所有行星的轨道都很靠近地球的轨道平面? ?黄道面。 |
| 6. | It is because the plane of the lunar orbit does not coincide with the plane of the earth s orbit . so , for most full moons , the moon is either south or north of the orbital plane of the earth
原来月球的公转轨道平面和地球的公转平面并不一致，因此在满月时，月球通常不是在地球轨道平面之南，就是在其北，难得会进入位于轨道平面的地影内，所以大部分满月都不会出现月食。 |
