| May 26, 2021 at 22:46 | comment | added | DWKraus | Weird idea: Could the planet and moon be in some stable configuration between two + large bodies? Say a star and a super-Jupiter or small black hole? The star and black hole could orbit each other, with planet/moon wedged between. No idea how to do that math, though. If @Nuclear Hoagie has an idea, would love to hear what you all think. I'm creative, but a biologist. | |

The problem is that it is a "saddle", not a stable "cone". I'm doing some more research, but the "same size, light exposure pushes it back on track" idea is probably enough to make it plausible. | |
| May 25, 2021 at 22:34 | comment | added | Arimeris | Thanks! I have edited my original question and added another approach to my idea, I would appreciate it if you gave it a go as well. I have one more idea that involves a geo-centric system, but I think that's too far removed from the original topic and requires a different question... | |
