Axial precession - Wikipedia
https://en.wikipedia.org/wiki/Axial_precessionThe images at right attempt to explain the relation between the precession of the Earth's axis and the shift in the equinoxes. These images show the position of the Earth's axis on the celestial sphere, a fictitious sphere which places the stars according to their position as seen from Earth, regardless of their actual distance. The first image shows the celestial sphere from the outside, with th…

https://fr.wikipedia.org/wiki/Précession_des_équinoxesLa précession des équinoxes est le décalage progressif de la direction où sont vues les étoiles, d'un siècle à l'autre, à raison d'une rotation complète, tous les 26 000 ans environ, effet produit par un lent changement de direction de l'axe de rotation de la Terre, dans la même durée.

https://en.wikipedia.org/wiki/Precession- Precession is a change in the orientation of the rotational axis of a rotating body. In an appropriate reference frame it can be defined as a change in the first Euler angle, whereas the third Euler angle defines the rotation itself. In other words, if the axis of rotation of a body is itself rotating about a second axis, that body is said to be precessing about the second axis. A motio…

https://simple.wikipedia.org/wiki/Stellar_precessionAstronomers have known about this movement for a very long time, calling it the precession of the equinoxes. Most people think that Hipparchus discovered it in ancient Greece in about 130 BC , but some people think that even the ancient Egyptians may have known about it.

https://en.wikisource.org/wiki/1911_Encyclopædia...PRECESSION OF THE EQUINOXES, in astronomy, the term assigned to the progressive motion of the equinox, because it takes place in a direction from east towards west, opposite to that in which planets move, and in which longitudes are measured. The equinox being defined as the point of intersection of the equator and ecliptic, its motion arises ...
