Nutation

Nutation is the name given to a slight oscillatory movement noticeable in the celestial pole of the earth, due to the latter not being a perfect sphere. It is worth mentioning here that the celestial poles of the Earth are the points where Earth's axis of rotation is extended infinitely and intersects the celestial sphere. The north celestial pole of the Earth is directly above its North Pole, and the south celestial pole is directly below its South Pole.
