Kepler-452b: Moons?

[_Augustus_]

So I've been wondering about the upper mass constraints for a moon of Kepler-452b (possibly for a sci-fi project, wink-wink). Is there a formula to calculate the upper mass constraints of a moon?

No idea about mass constraints, but there are some laws to predict orbits of moons and planets, maybe this will help you

Yet some people in here thinks it is pseudo-science, so be careful

Upper mass constrain would likely comes from the total mass of the system (as it'll be pretty much like Moon - Earth, where the actual keplerian orbit of Earth - Moon system is the orbit of the barycenter and not Earth's center). Then you have hill sphere, constraining the distance from parent planet. From there, you can have a constraint where it won't be a binary planet (ha, pluto-charon "copy" at a distant star !) and density constraint (because we knew the planet radius already). Lastly you can work out whether tidal locking already happens or not, so we know whether somone can live nicely there.

I noticed several articles on the subject the other day while doing some searches for papers on the latest Earth-2 find. Here's a sample -
