Y'all should know by now that I want to build a Death Star ;-)
Let's assume that we did that already -- and against the odds, we've built two of them, and they're currently in orbit around a planet; let's say planet Earth.
What would happen to our planet if two extra [metal] moons joined our orbit?
- Tides would probably be affected; how?
- Would sunlight patterns be affected?
- Would there be differences if these gargantuan constructs stayed in place over one spot, or if they had a moon-like orbit?
- Anything other major effects that I'm missing?
