In these days Polaris is called the North Star because it remains stationary above the north pole and all other stars appear to move around this planet earth. In 3,000 BCE the North Star was Thuban and 2,ooo years from now it will be Alrai. This slow change in the angle of the Planet Earth’s axis also causes the constellations of Paa Danderah “The Zodiac” to change their position in the night sky relative to the vernal spring equinox.
