Yarn VI.6.C

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

Yarn VI.6.C is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 55.96 time units, published by Šuvakov & Dmitrašinović (2013). Dense skeins of thread wound around a hollow core. It is weakly unstable (largest Floquet multiplier 4.993), so a small nudge makes it unravel over a few periods. The bodies pass within 0.00502 of each other at a top speed of 14.2, line up 48 times a period, and the computed loop closes to 8.4×10⁻²⁵.
