因为有卫星的头衔，而且沿椭圆形轨道环绕地球运行，月亮似乎每天平均51分钟返回到天空的同一地点。
Due to the moon's titled and elliptical orbit around Earth, the moon seems to return to the same place in the sky 51 minutes later each day, on average.
这意味着，即使这个星球有类似地球的卫星，它们也不可能承受得了天苑四b椭圆轨道带来的极端温度变化。
That means that, even if the planet has terrestrial moons, they likely wouldn't be able to stand the extreme temperature swings that go along with Epsilon Eridani b's eccentric orbit.
