Try different "acceleration" and orbit speeds.
Two orbiters with a line drawn between them. The speed of the orbits is slightly different. You can set the fixed speed for orbiter 1. Orbiter 2's speed changes with "acceleration." Often a heart shaped cardioid pattern forms. Based on my several planetary orbit projects, which are better because based on real orbits in our solar system. In this project, the two orbiters have the same radius (if they were planets they would collide) and one orbiter gradually accelerates (speed increases).
