On this foundation, fix the reference frame on the stator current vector and rotate synchronously ( stator current orientation).

Small planets close to their parental stars risk becoming tidally locked: that is, the lengths of their days come to match their orbital periods, and they thus have one permanently hot hemisphere and one that is permanently cold.

接近它们母恒星的小行星会有发生潮汐加热的风险：即，这些小行星上白天的长度会与它们的轨道周期相对应，因此，它们的一半会永远炎热，而另一半会永远寒冷。

Just as Mercury is locked facing the sun, the planet is tidally locked to its star, so that one side basks in perpetual daylight, while the other side remains in darkness.

与水星总有一半固定地面对太阳相似，该行星总是始终保持一面朝向恒星，使得星球的一半永久处于阳光之中，而另一半则永久位于黑暗。
