# Successive Refinements in Long-Term Integrations of Planetary Orbits

@article{Varadi2003SuccessiveRI, title={Successive Refinements in Long-Term Integrations of Planetary Orbits}, author={F. Varadi and Bruce Runnegar and Michael Ghil}, journal={The Astrophysical Journal}, year={2003}, volume={592}, pages={620-630} }

We report on accurate, long-term numerical simulations of the orbits of the major planets in our solar system. The equations of motion are directly integrated by a Stormer multistep scheme, which is optimized to reduce round-off errors. The physical models are successively refined to include corrections due to general relativity and the finite size of the lunar orbit. In one case, the Earth-Moon system is resolved as two separate bodies, and the results are compared with those based on…
