[QUOTE=bojan;1450561]Yep...
Can I offer some badly needed education on precession, see here:
https://en.wikipedia.org/wiki/Precession
Yes Bojan I agree, on the presumption that some contributors may not be familiar with all details of the precession of the equinoxes, a fundamental factor of planetary motion.
For example, precession of the equinoxes is a demonstration that Earth's orbit is a spiral motion that progresses the orbit about the plane of the ecliptic and the North pole cycling about the pole of the ecliptic. This spiral orbital motion of our. planet seems not to be fully recognised.
