It is generally believed that Venus originated with the typical fast and direct rotation. But in the late evolution process, as a result of atmospheric tides and core-mantle friction inside the planet, the rotation is changed gradually. While some others considered that the change of Venus'rotation perhaps due to the early giant planetesimal's collisions.

一般认为，金星原来具有典型的快速正转的状态，在后来的演化过程中，由于潮汐作用或行星内部流体核与幔间的摩擦作用，使得自转逐渐发生变化；也有研究认为可能是早期受到大星子的偶然碰撞所致。
