Based on my own heuristic studies of orbital characteristics it's very easy for me to speculate that all the planets in our solar system are in chaotic orbits, particularly if you factor in a sufficient amount of geological time into the equation. IOW, it's a very slow process, for the most part. Nevertheless, chaos may be the norm, not the exception. Seems to me that chaos could also explain a lot of dramatic climatic changes our planet has experienced since it first formed 4.5 billion years ago. Just another wobble, give or take several million years. Regards, Steven Vincent Johnson www.OrionWorks.com www.zazzle.com/orionworks
