Triton

Neptune's moon, Triton, orbits close to Neptune in a circular orbit. However, it orbits in the opposite direction of Neptune's other inner moons. The simulation triton.gsim shows Triton in its retrograde orbit. The initial starting conditions were obtained using data from JPL's Horizons Ephemeris Computation Service.
