Precession

Precession is a phenomenon in which the rotational axis of a spinning object, such as a planet or a spacecraft, moves in a circular path over time. In space and astronautical engineering, precession is an important consideration for spacecraft attitude control and navigation. The precession of a spacecraft's rotational axis can be caused by external torques, such as gravitational forces from other celestial bodies, or internal torques, such as those generated by reaction wheels or thrusters. Understanding and predicting precession is crucial for maintaining the stability and accuracy of spacecraft operations, including communication, imaging, and scientific measurements.
