I'm looking for Trojan asteroids at Earth's LFive Lagrange point.

在地球的L5拉格朗日点寻找特洛伊小行星。

Other stars have occupied the pole position, and sometimes the extended North Pole of the Earth points at empty space.

其他恒星占据了极点位置，有时地球的北极延伸指向空旷的太空。

And that it, so if you imagine the extended North Pole of the Earth pointing up at the sky, in our time, it's pointing at the star, Polaris, and that is our pole star.

就是这样， 所以如果你想象地球的北极延伸指向天空，在我们的时代， 它指向的是北极星，那就是我们的北极星。
