Hello /sci/
I am building a little system and need to determine how long two moons of the same planet would have line of sight to each other. For this I need to know the angle β.
Is there a way I can figure it out if α, the radius of the planet r1, the distance of the inner moon r2 and the distance of the outer moon r3 are known?

That site seems to be about rocket technology. It doesn't seem to hold answers for my geometrical problem.

Not him but they probably meant to link you to the orbital mechanics page on the left side of the site.

www.reddit.com/r/askmath is an infinitely better place to ask legitimate questions. This board is for cancer.

Just saw that, reading the words "moon hoax" must have put me in a bit of dismissive headspace.
I'll scour that.

beta is twice alpha
that orbit should be an ellipse
read about keplers laws etc,

There can be a case where α=2β. But as the radii can vary in length and proportion to each other (example picture related α ~62,5° β ~80°), this isn't the solution.
Working with semi-major axis. And considering I choose the orbits, it might as well be perfect circles for now.
