Earth processional axis
WebThe fact that the Earth’s axis precesses has been known since ancient times. After Newton developed the laws of motion and gravity, he tried to account for the precession. He … The precession of the equinoxes is caused by the gravitational forces of the Sun and the Moon, and to a lesser extent other bodies, on the Earth. It was first explained by Sir Isaac Newton. Axial precession is similar to the precession of a spinning top. In both cases, the applied force is due to gravity. For a spinning top, … See more In astronomy, axial precession is a gravity-induced, slow, and continuous change in the orientation of an astronomical body's rotational axis.
