Three-Body problem for the earth-moon system under photo-gravitational influence of the sun

Polish astronomer K. Kordylewski has discovered the clouds of interplanetary dust in the neighborhood of the triangular libration points of the Earth-Moon system. More than 60 years after the first observation the existence of these elusive clouds is still disputed. Due to the unavoidable perturbations, such that the influence of the Sun, the triangular libration points have to be unstable. In the perturbed three body problem, we show the possibility of the existence of four dust clouds, moving along the stable periodical orbits, capturing the Lagrange libration points, and discuss the best conditions to observe them. © 2017 Univelt Inc.
