The restricted three-body problem is historically significant and remains open to this day. This project investigates the orbital stability of a third body in the planar restricted three body problem by exploring the behavior of an infinitesimal mass near the Lagrangian points of a two body system of varying mass ratios and eccentricities of orbit. Using numerical methods we record the behavior of the infinitesimal mass in a grid of initial positions in order to create maps of the regions of stability and instability in the proximity of the Lagrangian points and the center of mass of the system. We perform our computations using a rotating-pulsating coordinate system and a high precision numerical algorithm for accurate simulations of the orbit of the infinitesimal mass. Ongoing research includes investigation of increasing computational performance of numerical methods for the restricted three body problem using parallel processing on the CUDA architecture.
