Artificial intervention (in the form of a massive, powerful, steerable moon) would be required to keep it centered, and it's hard to imagine how it ever got to be there in the first place... | |

As to the black hole, sure, why not? it's just a mass | |
| Jan 30, 2016 at 19:48 | comment | added | sh1 | I think that's L1 you've used for your planet, right? Does this imply that you can have objects at L4 and L5 that subjectively appear to also be orbiting the planet, or do those disappear when both major bodies are the same size? And can we replace one star with a black hole of the same mass? | |
