Perspective - It’s the Earth that’s moving, space is standing still
The Earth takes roughly 24 hours to spin on its axis, moving from east to west. But, do stars move?

If you watch the sky over a few hours in most locations on Earth, you can see the same thing happening: stars rising in the east, and setting in the west. There are some exceptions to this rule, however:

Stars that are close to the Earth’s axis of rotation — what we call the north and the south pole — rotate around the poles. If the pole’s location is far enough above the horizon, some stars never set. They just keep spinning.

If your geographical location happens to be close to the pole, most stars will be rotating around the pole and very few will rise and set. (And in a trick of geometry, it will be hard to see the Sun, moon and planets since their path in the sky is at 23.5 degrees — the same as Earth’s tilt. This is why the poles have months of darkness, because the Sun doesn’t always shine there.)
