From the developer:
ThreeBody illustrates some solutions of the 3 bodies problem in celestial mechanic.
ThreeBody illustrate 3 cases in the situation where the 3 planets have the same mass. The two first cases are "classical" ones and very special in the sense that the trajectories are close and "stable": Case of Lagrange (18the century), Case of A. Chenciner & R. Montgomery (1999) and Arbitray case.
You may want to check out more software, such as Maxima and Minima, IUCLID5 or ECoord, which might be similar to ThreeBody.
