Yin-Yang III.3.Aβ

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

Yin-Yang III.3.Aβ is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 10.963 time units, published by Šuvakov & Dmitrašinović (2013). Two interlocking halves whose lobes wrap around each other. It is weakly unstable (largest Floquet multiplier 1.905), so a small nudge makes it unravel over a few periods. The bodies pass within 0.00979 of each other at a top speed of 10.2, line up 20 times a period, and the computed loop closes to 3.1×10⁻²⁸.
