WebIn astronomy, the plane of the Sun's apparent orbit relative to the Earth is known as the ecliptic plane. Let us define non-rotating Cartesian coordinates, centered on the Earth, which are such that the - and -axes lie in the ecliptic plane, and the -axis is normal to this plane (in the sense that the Earth's north pole lies at positive ).

WebApr 4, 2024 · It reacts to the the gravitational influence of the sun and moon like a spinning top whose rotation is distorted by some external force: this causes what has been termed the earth's precession - which means that the earth's axis itself rotates in a circle, leading to a conical movement around the fixed pole of the ecliptic. In astronomy, precession refers to any of several gravity-induced, slow and continuous changes in an astronomical body's rotational axis or orbital path. Precession of the equinoxes, perihelion precession, changes in the tilt of Earth's axis to its orbit, and the eccentricity of its orbit over tens of thousands … See more Precession is a change in the orientation of the rotational axis of a rotating body.
