### How would a cube-moon orbit a Cube-World with uniform surface gravity?

I'm not even going to try to work out the math, but the simple rules of thumb seem to me to be: The basic rules of "mass" still apply. All the mass within a sphere, regardless the shape of ...

### How would a cube-moon orbit a Cube-World with uniform surface gravity?

The mass distribution will affect either body, but only to a small margin not enough to change the orbit's shape visibly In fact, what we calculate as gravity force is actually an integral by volume ...

### What would happen if there were nine lunar cycles in a year?

Maybe you should look up the Sliding Scale of Science fiction Hardness. https://tvtropes.org/pmwiki/pmwiki.php/MediaNotes/MohsScaleOfScienceFictionHardness And then decide what score on that scale you ...

### What would happen if there were nine lunar cycles in a year?

Probably lower tides Assuming that this alternate Earth does not dramatically change the gravitational constant or the value of pi, the orbital period of this Earth's moon is dependent on two values ...

### Long-term stability for a terrestrial planet with rings and a large sub-synchronous moon

Plausibility of the scenario & options I have given the original idea more thought. I try to elaborate in the second part about the Roche limit. If you would like to have additional info, see this ...

### Long-term stability for a terrestrial planet with rings and a large sub-synchronous moon

A (recent!) comet-encounter caused the creation of the rings. Plausibility issues I agree with your assumption of the rings being prone do get ejected quickly because of the influence of the moon. But ...

### Would tidal recession significantly reduce the angular size of small moons?

My gut instinct is that a moon system this complex is not actually orbitally stable over geological time to spite your simulation. Thinking on it the reasoning behind that feeling is simply that the ...

### Would tidal recession significantly reduce the angular size of small moons?

If your focus is really just on the distance those moons would move away from their host planet, you could argue what you want, essentially. It is dependent on how the moons formed and the ...
