I have a situation where I have proceduraly generated planets and moons in a solar system. These bodies have varying mass and radius.
Now what I want to do is be able to define a circular orbital path around each (Planet and Moons) that would be conceptually equivalent to Low Earth Orbit, High Earth Orbit, and Geosynchronous Earth Orbit.
I don't want to get into high math calculating things exactly, and like I stated previously these orbits are circular not elliptical anyway. What I do need is really just a way to fake it so it seems somewhat logical and semi-believable.
Does anyone have any idea on how I might best go about this? I would guess that the main, or maybe only necessary, variable in the equation would be the mass of the planet or moon?
Also as a side but semi-related question would there be something similar I should take into account when placing moons around a planet to keep it semi logical?
Thanks for any help!
