WebOct 31, 2024 · The Physical Cause of the Precession. The daily motion of the stars around the north celestial pole is, of course, a reflection of Earth’s rotation on its axis; and the annual motion of the Sun along the ecliptic, which is inclined at \(23^\circ .4\) to the celestial equator, is a reflection of the annual orbital motion of Earth around the Sun, the plane of …
