It is purely coincidental that the north star Polaris happens to be fairly close to the north celestial pole in the skies. In fact, the Earth's rotation wobbles very slowly - called "precession" - over a span of 25,800 years. In about 3000 years, the north pole won't be pointing to Polaris, but to some other spot in the sky, and there will not be a "pole star".
In about 12,000 years, the "pole star" will be Vega, and in 24,000 years it will be back to Polaris again.
Because the precession is so slow, no human lives long enough to notice any changes.

What is the altitude of the north celestial pole if You live at a latitude of 28 degrees North?
The asterism called the "Big Dipper" (which is the central part of the constellation named "Ursa Major") has two fairly prominent stars which act as a pointer to the north star Polaris. Polaris is a relatively dim and undistinguished star whose positioning almost directly above the north pole is very conveniently located in the sky.
What cause the north star to change between the stars vega polaris and thuban?
The Earth is like an enormous gyroscope, spinning in space. We think of gyroscopes as always pointing in the same direction, but all gyros wobble a little bit, with a motion called "precession". The Earth's precession causes the north pole to move VERY SLOWLY. The north pole of the Earth is currently pointed to the star Polaris, but it hasn't always been, and won't always be. The cycle is 25,800 years long.As the centuries pass, the Earth's precession will cause the north pole to slowly move away from Polaris, and in about 12,000 years will point somewhere near Vega. In another 14,000 years, the north pole will be pointed somewhere near Polaris again - except that Polaris itself is moving. In 26,000 years, Polaris will be about 5 degrees away from the pole.

Polaris, also called the North Star and the Pole Star, is situated within about 2/3 of a degree of the North Celestial Pole.
What star does not change its position with the seasons?
The bright star Polaris in approximately aligned with the Earth's axis of rotation and therefore does not change its seeming position when seen from the Earth, no matter the time of day or the time of year. It is always towards North. When you stand at the North Pole, the star will be approximately directly overhead.There is no similar, bright pole star for the southern hemisphere.
