There have been two recent subjects dealing, according to my understanding, with the matter of precession:
In the first "Two Questions" Jeff Atkins pointed to the site: http://riemann.usno.navy.mil/AA/faq/docs/seasons_orbit.html that refers to the period that the major axis of the Earth's orbit to rotate through 360 degrees. This period is about 21,000 years. Under the heading "Length of the year" the period of precession is given as 26,298 years and I have that figure from other sources. Am I correct in thinking that these are two seperate long term effects?
