Any alteration in the position of a celestial body's rotation axis is known as precession. Astronomical bodies naturally feature slow changes in both their rotational rate and orbital status around other gravitationally-strong bodies. Two types of precession exist within the realm of astronomy: torque-free and torque-induced. According to the mathematical principles of torque-free precession, the rotating axis is different from the ellipse of an object. In the case of torque-induced precession, the object maintains an alternating rotation. The most common example of this phenomenon can be…
