An analogous concept applies to other planets: a planet's celestial poles are the points in the sky where the projection of the planet's axis of rotation intersects the celestial sphere (the apparent positions of the stars also change slightly due to parallax effects).
An analogous concept applies to other planets: a planet's celestial poles are the points in the sky where the projection of the planet's axis of rotation intersects the celestial sphere. These points vary because the planets' axes are oriented differently (the apparent positions of the stars also change slightly due to parallax effects).
