Additionally, Why is the North Star so important? The North Star or Pole Star – aka Polaris – is famous for holding nearly still in our sky while the entire northern sky moves around it.

FAQ
Why do stars twinkle?
As light from a star races through our atmosphere, it bounces and bumps through the different layers, bending the light before you see it. Since the hot and cold layers of air keep moving, the bending of the light changes too, which causes the star’s appearance to wobble or twinkle.
Is the North Star a red giant? Polaris is in the stage of being a red giant. The roman numeral for Polaris is II which means its a giant with a low mass.In this stage hydrogen is being made into helium and helium is also combining to form carbon which means it is slowly starting to burn denser elements.
