The North Star, or North Star, is if not the most important navigational star because its position in the sky is almost exactly aligned (within a few degrees) with the Earth’s axis of rotation. This means that it doesn’t matter where you are on Earth (as long as you are in the Northern Hemisphere); if you are facing the North Star, you are facing North. Finding the North Star is an incredibly useful and simple nighttime navigation technique that has helped everyone from the Egyptians to the Vikings find their way on the open sea.
