Nobody here can answer your concern, because all they have at their disposal is the main faq, which does not address many other important issues.
To start with, the three body problem cannot be explained using the conventional approach: attractive gravity. That is, a system consisting of a star (Sun), a planet (Earth), and a satellite of the planet (Moon) cannot be described mathematically; this fact was discovered long ago by Henri Poincare, and was hidden from public view:

An attractive gravity field, made up of gravitons, cannot explain at all the three body problem, here is another demonstration:
http://theflatearthsociety.net/talk/viewtopic.php?f=7&t=1183&start=15#p35542It is very important to understand the existence of two types of gravitational energies: terrestrial gravity and planetary/stellar gravity.
Here is I. Newton describing these facts:
Here is a letter from Newton to Halley, describing how he had independently arrived at the inverse square law using his aether hypothesis, to which he refers as the 'descending spirit':
....Now if this spirit
descends from above with uniform velocity, its density and consequently its force will be reciprocally proportional to the square of its distance from the centre. But if it descended with accelerated motion, its density will everywhere diminish as much as the velocity increases, and so its force (according to the hypothesis) will be the same as before, that is still reciprocally as the square of its distance from the centre'
And now, Newton's explanation for the cause of the orbits of the planets/stars:
Isaac Newton speculated that gravity was caused by a flow of ether, or space, into celestial bodies. He discussed this theory in letters to Oldenburg, Halley, and Boyle.
Newton still thought that the planets and Sun were kept apart by 'some secret principle of unsociableness in the ethers of their vortices,' and that gravity was due to a
circulating ether.Pressure Gravity = Terrestrial Gravity
Rotational/Circulating Gravity = Planetary Gravity
Therefore, between these two types of gravitational energies (aether = medium in which ether flows; ether = telluric currents; density of aether varies greatly) there must exist a barrier which separates them, the terrestrial gravity from the rotational gravity. We can call this barrier the Schumann cavity; this is the very reason that no Nasa mission could go beyond this energy field.
The experiment performed by G.B. Airy in 1871 confirmed these hypotheses; convince yourself that this is indeed the case:
