Quizplus · Accepted Answer

Earth's rotation is connected with precession, a very slow celestial motion that can be detected only over centuries. This is because the Earth's axis slowly wobbles due to gravitational forces exerted by the Sun and the Moon, causing the positions of the stars to change gradually over a long period of time.
