Abstract: | The starting point of our study was the recent results of Alain Chenciner and Richard Montgomery concerning the discovery
of the 8-shaped orbit of the planar 3-body problem with equal masses (in the sequel, we will call it just “the Eight,” 4]).
Geometrically this orbit consists of 12 pieces such that each of them minimizes the Lagrangian action between Euler and isosceles
configurations of the bodies. Our aim was to understand whether the larger pieces of the Eight are still solutions of some
minimizing problem. The paper presents some preliminary analytical and numerical results on the minimizing properties of the
Eight. Using the technique of the so-called Jacobi curves, we numerically show that the solution of Chenciner and Montgomery
is no longer optimal after 0.52 of its period. Moreover, we find a better solution for the fixed endpoint problem.
