What are the details of a stable two moon orbit?
Sorry for the long answer,but read on… You will be surprised and amazed ! A stable system consisting of one planet and two moons can take many forms, some of these have know examples in the solar system. I will assume you are are asking the question in relation to small planets (such as Earth) not Gas Giants which are known to have complex systems of moons orbiting them) Starting with the easiest one, you can have a stable system if the two moons are small relative to the size of the planet. One example of such a system is Mars, which has two moons Phobos and Deimos. Orbital details are published and easily available. Both moons are visible from the surface. It is also possible to obtain a stable system if one of the moons orbits much further. This far-away moon feels the effect of the plant + close-moon system as if they were approximately one single body. I can’t think of one example where this involves only 2 moons, but for example Pluto as a large moon (Charon) orbiting close and
