How to find data on Earth, planets, motions

  1. Apr 18, 2008 #1
    I am studying the problem of ice ages and I wonder how do I find, in what form the most modern, "official" data about motion of earth through space? Presumably this includes data about whole solar system for calculating perturbations.

    As I understand that set of data should give all different periods such as variation in eccentricity and others.
