If the northern hemisphere you happen to watch the sky on a clear night and draws the eye to the North, the horizon at a height equal to the latitude of the place where you are, you will see the North Star. It is not very bright but very important because it indicates a direction: The direction of the North Pole or the North. This characteristic, since ancient times when there was no compass, has meant that the sailors were able to steer the bow toward the expected target. Even now we measure the height of the pole star to get an indication of the latitude where you are.
Since its creation, the North Star is still motionless in the sky to indicate the north of the northern hemisphere. Does not grow and never fade. Disappears during the day only because aside from sunlight.
All the stars and the planets revolve around the pole star which is the center of rotation of the sky of the northern hemisphere!
When I get lost in the starry nights in the depths of the galaxy rest charmed by the harmony and poetry that gives us the universe and the laws that regulate it.
