Symplectic Integrators for Solar System Dynamics
Abstract
Certain symplectic integrators relevant to solar system dynamics are defined here. It is shown that the dominant long-term error arises from a constant error in the mean motion, and special starting procedure which can eliminate this error are described. The resulting improvement make these integrators easily the best available for a wide range of solar system problems.
