This is called retrograde motion, and in a sense it means Venus's north pole got swapped with its south pole: it flipped over.

这被称为逆行运动，在某种意义上，这意味着金星的北极和南极交换了：它是颠倒的。

Many astronomers theorize that the extremely slow rotation, coupled with retrograde motion, makes a challenging for any moon to have a stable orbit around this planet.

许多天文学家推测，极慢的自转和逆行运动使任何卫星都很难在这颗行星周围有一个稳定的轨道。

One of the bizarre things about Venus, from a rotational dynamics perspective, is that it moves in retrograde motion, that is, it rotates in the opposite direction to the rotation of most other planets.

从旋转动力学的角度来看，金星的一个奇怪之处在于它以逆行运动的方式运动，也就是说，它的旋转方向与大多数其他行星的旋转方向相反。
