Can you see the Big Dipper on the moon?

Several questions are very representative.

We determine that the celestial coordinates are based on the earth axis and the equator. On other planets, it is generally impossible to determine the position of a constant star with the coordinate system on the earth, so the Polaris determined by the earth is probably not the Polaris of other stars. But the starry sky is still this starry sky, and the relative positions between the stars are still the same, so the constellation is still applicable.

Unless you go to other parts of the galaxy far away from the solar system, the starry sky there is different from here, and the constellation system is not applicable.

Uranus, on the other hand, its north pole is not always facing the sun, so the sun is not the so-called north star. No star in the solar system always faces the same side of the sun.
