Yin-Yang III.16.Aα

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

Yin-Yang III.16.Aα is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 80.149 time units, published by Šuvakov & Dmitrašinović (2013). Two interlocking halves whose lobes wrap around each other. It is weakly unstable (largest Floquet multiplier 1.229), so a small nudge makes it unravel over a few periods. The bodies pass within 0.000366 of each other at a top speed of 52.3, line up 110 times a period, and the computed loop closes to 1.1×10⁻²⁴.
