Hi all,
As the sun is an oblate spheroid and is rotating, should not the axis of rotation be precessing, much like the Earth does?
What is the axial tilt angle and what is the precession period in years? Also, what is the amplitude and period of the nutation? Are there are equations for estimating these values for different configurations?
Thanks,
Natski
