Although there is no solution for the general three body problem there are many related results, especially for the restricted case. <a href="https://arxiv.org/abs/1106.5062"> Here is a study of LE's</a> in restricted 3BP. <a href="https://arxiv.org/abs/1205.0950">And here is a classification scheme</a> for the mean motion resonance of the restricted 3BP including using the maximal LE for characterizing the resonances. These will point you to many related results. As a historical aside, Gutzwiller, in his book[1] says that the ancient Greeks knew there were 3 different lunar months (depending on how you measure them in they sky): the Sidereal month (27.32166 days), the anomalistic month (27.55455 days) and the nodical month (27.21222 days). These result from 3 body interactions (earth, moon, sun). The Greeks were apparently able to observe these to an accuracy of 1 second per month. Gutzwiller calls these the first precision scientific measurements in history. Every time I think about this I am astonished; it must have taken immense effort over centuries to compile the needed data. [1] Martin C.
