What is the other name for North star?

Pole Star. Polaris is currently the pole star of our blue planet Earth.

Explanation

North Star is the brightest star that appears nearest to either celestial pole at any particular time. The star is called the north star because it sits in the direction that the spin axis from the Northern Hemisphere of Earth points. Pole star belongs to Ursa Minor constellation. An apparent magnitude of 1.97, it is the brightest star in the Ursa Minor constellation. At present, the star known as Polaris is the North Star. However, Polaris has not always been the North Star and will not always be the North Star. To understand that, we need to look at how the Earth spins on its axis.
