A new solution is numerically determined for the obliquity of the ecliptic and the longitude of the perihelion measured from the equinox of date. For the eccentricity, the longitude of the perihelion measured from the equinox of epoch, the inclination and the longitude of the node, the solution by Bretagnon (1974) has been used. For the obliquity and the precession in longitude, Sharaf's (1967) analytical expansions are used. Parameters of the expansions are tabulated and a graphical representation extends back to 5000000 years before the present and forwards to 10,000,000 years after the present.
