Earth orientation parameters (Earth 🌍)

In geodesy and astrometry, earth orientation parameters describe irregularities in the rotation of planet Earth. EOP provide the rotational transform from the International Terrestrial Reference System to the International Celestial Reference System, or vice versa, as a function of time. Earth's rotational velocity is not constant over time.
