WebbBut regardless, what Hipparchus had discovered was the precession of the equinoxes which refers to the shifting of the earth’s position in its orbit on a given date at a rate of 0.014 degrees per year or 1/100 th of a degree per year. Now, theres a reason why this happens; which Hipparchus didn’t completely figure out but he had some ideas ... 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 of years are all important parts of the astronomical theory of ice ages. (See Milankovitch cycles.)

WebbPrecession of the equinoxes came to the fore while Hipparchus investigated the constancy of the year, by timing successive equinoxes.
