Is it possible to estimate the 23.5° tilt of Earth's axis?
Using the value of the precession of Earth's axis in 25,800 years and the value of Earth's radius, mass, moment of inertia etc., would it be possible to calculate/estimate that Earth's axis must be ...

Are the precession and nutation of Earth's core directly connected with precession and nutation of Earth's magnetic field if they are present?
If the magnetic field of Earth is generated in the core of the Earth can we deduce core's precession cycle by measuring the precession of Earth's magnetic field (not Earth as a material object) or the ...

Why is the centre of Earth's axial precession perfectly perpendicular to the ecliptic? (is it?)
It is my understanding that the Earth's axial precession is such that the line of the North pole pointing away from the planet traces out a circle on the celestial sphere with a period of roughly 26,...
