The Earth's celestial poles are the two points in space where the Earth's axis of rotation intersects the celestial sphere. They are the apparent centers of rotation for the stars, with the North Celestial Pole being at a declination of ( 90^{circ }) and the South Celestial Pole at (-90^{circ }). As the Earth spins, the stars appear to revolve around these fixed celestial poles, which are currently marked by the stars Polaris in the north and the opposite point in the south | Mark Penberthy Corn
