Yin-Yang III.12.Aα

From Šuvakov & Dmitrašinović (2013). Sequences of orbits from the Belgrade three-body gallery.

Yin-Yang III.12.Aα is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 55.789 time units, published by Šuvakov & Dmitrašinović (2013). Two interlocking halves whose lobes wrap around each other. It is linearly stable (largest Floquet multiplier 1.000), so a small nudge only makes it wobble. The bodies pass within 0.000195 of each other at a top speed of 71.6, line up 80 times a period, and the computed loop closes to 4.2×10⁻²⁵.
