I can find information on the cyclic deviation of the eccentricity of earth’s orbit, but information on the other planets I’ve yet to come across. Is this simply not published or published in something more advanced than the very general material I’ve already consulted?
Thanks.
I can’t think of a specific reference, but there will be numbers in the specialist literature. Aside from the whole tradition of calculating these things perturbatively - the issue’s been central to celestial mechanics since the likes of Laplace and Lagrange - there’s a whole subfield of running computer simulations of the Solar System over very, very long timescales. They traditionally report their results in the form of periodic (or, horror!, secular) changes in the orbital elements. Though the fashionable stuff in the area over the last decade or so has been finding chaos in them.
