The pole star is situated on the axis of rotation of the earth as shown in the diagram below. When the earth rotates on its own axis, the pole star ‘appears’ to remain stationary because the position of the earth isn't changing much with respect to the star. So no matter where we are on the earth and no matter what the time is, the position of the pole star will always be on this axis. This is not the case with the other stars in the galaxy. Also the pole star is only visible from the northern hemisphere.

However, this will not last forever. Over thousands of years, the earth’s axis also rotates (wobbles) slightly. This is called ‘precession’ and will result in the pole star shifting. Then some other star, which lies on the axis of the earth at that time will become our new pole star

⟹ when we look forward the pole star it appears stationary because it is pointing exactly on the north direction,,,,,.. The earth spins on its exist and the pole star is almost exactly above the exist of the earth that's why its appear stationary.
