I spent a long time playing with the sim. Nice work.
Most of the random data sets that I ran ended up with a two body system, where the third body was flung far into space never to return. However, some of these were misleading. I had one running for 15 minutes at 5x, and the third body did eventually return.
- jgchaos 10mo agoIt might be fun to add some kind of visualization showing when a body has enough energy to potentially escape the system.
- pylotlight 10mo agoQuestion, can you mathmatically plot a trajectory across time X and energy required to see when it's met and how long it would take given a start position or something? Or is the simulation so complex that you can never project. Oh never mind I see answers to this elsewhere here, cheers.
- JKCalhoun 10mo agoAgree. I was hoping perhaps it would "flash" or do something visually different to indicate "Bye bye!"

Real three-body orbital systems show this same behavior. Consider that such a system must obey energy conservation, so only a few extreme edge cases lose one of its members permanently (not impossible, just unlikely). Ironically, because computer simulators are based on numerical DE solvers, they sometimes show outcomes that a real orbital system wouldn't/couldn't.
- moi2388 10mo agoI don’t understand. How would energy not be conserved if one flew away? It’s not in the system, but it’s still out there?
- lutusp 10mo agoI'm just saying that, because of energy conservation, an escaping member would need to permanently carry away more than 1/3 of the system energy (for equal-mass satellites). This is possible but unlikely.
