And, by coincidence, there's also a middling-bright star that sits very close to the north celestial pole.

巧合的是，还有一颗中等亮度的恒星非常靠近北天极。

A star right on the celestial pole wouldn't appear to move at all, and would just hang there, like it was nailed to that spot, all night long.

一颗在天极上的星星看起来不会移动，只是挂在那里，就像被钉在那点上一样，一整夜都是如此。
