👉 In celestial mechanics, a precessional orbit is an orbit in which the plane of motion (i.e., the plane between the earth's orbit and the sun) is inclined relative to the direction of motion. The inclination of this plane is determined by the tilt of the Earth's axis relative to its orbital plane.
The precessional orbits are often used to describe the behavior of celestial bodies in space, as they can be predicted from the laws of planetary mechanics. In particular, precessional
