Thanks Rob (from another Rob). Your explanation was very concise and clear. Especially having just read Ron's reply. As I told Ron, I'm going to have to spend some time daydreaming about it to get it comfortable in my head but I at least understand the physics now. There was me thinking it may have something to do with general relativity. I always doubted this because of the low masses and velocites involved. As for Isaac Newton, I still think he'd be grumpy about it all. His equations are only really much good in a 2 body situation. As I understand it, 3 bodies are a nightmare and ultimately unpredictable, though I don't know why, exactly.
Once again, wonderful answers to my questions. I can go to bed now, content that I am a little smarter than when I woke up.
