Earth axis wobble period
WebIn astronomy, axial precession is a gravity-induced, slow, and continuous change in the orientation of an astronomical body's rotational axis.In the absence of precession, the astronomical body's orbit would show axial parallelism. In particular, axial precession can refer to the gradual shift in the orientation of Earth's axis of rotation in a cycle of … WebApr 28, 2024 · As glaciers melt, water mass redistributes, causing shifts in the planet's axis.
