Concept:The Pole Star (also called Polestar) is the star that lies exactly above the Earth’s North Pole along its axis of rotation.Explanation:The Earth spins on its axis. If a star is positioned exactly where the axis meets the sky, it appears fixed. That star is the Pole Star.It always remains in the northern direction. From Earth, it does not rise or set like other stars. So it is used as a guide to find north. Because of this, the Pole Star is known as the North Star.Other names include Polaris, Lodestar, and Guiding Star. It is not located in the south, east, or west.
