How is pole star different from other stars?

The pole star, also known as Polaris, is distinct from other stars primarily because it is located nearly directly above the North Celestial Pole, making it a pivotal point for navigation in the Northern Hemisphere. Unlike most stars that appear to move across the night sky, Polaris remains relatively fixed in position, serving as a reliable reference point. Additionally, Polaris is a supergiant star, which sets it apart in terms of size and brightness compared to many other stars.
