The Lagrange 4 and 5 points

The Lagrange 4 and 5 points are stable places where objects can share an orbit with a planet or moon. The simulation Lagrange uses a rotating frame to simulate objects captured in orbit around the Lagrange 4 & 5 points of a hypothetical planet orbiting close to the Sun. These objects trace tadpole orbits around the Sun. If their orbits had a little more energy, they would cross the Lagrange 3 point and enter a horseshoe orbit.
