This task involves integrating or implementing a system that can be used for simulating basic celestial mechanics.  One possible approach is to implement a particle system where mass properties can be assigned to objects and let the simulation drive position, velocity, and acceleration changes over time.  The simulation itself could be integrated into BRL-CAD's Archer modeling environment as a plugin that dynamically changes geometry (updating positions over time).

A third-party particle or dynamics system can be used for this project in leu of implementing one, but selection of such a system will need to be discussed beforehand to ensure compatibility and maintainability.  Something like [http://www.ode.org/ the Open Dynamics Engine (ODE)] or  [http://bulletphysics.org/ the Bullet Physics Library] can be used, but a proper particle or celestial mechanics system such as [http://libnova.sourceforge.net/ libnova] or [http://www-hpcc.astro.washington.edu/tools/changa.html changa] (which is unfortunately license incompatible) will probably be more appropriate given the physics involved.  MIT/BSD license is ideal.
