👉 In physics, a precession is a phenomenon in which an object experiences a slight change in its rotational motion due to the Earth's rotation. This can be caused by various factors such as the presence of other objects in orbit around the Earth or changes in the gravitational field of the Earth itself. The term "precessions" comes from the Greek word "peri," meaning "around." It refers to the phenomenon where an object rotates continuously, but it has a slight change in its direction of rotation
