Free-fall F32

(1, 0.8, 0.6)

From Li & Liao (2019)

Free-fall F32 (1, 0.8, 0.6) is a periodic orbit of the planar three-body problem: three masses in the ratio 1 : 0.8 : 0.6 that return to their starting positions and velocities every 5.6679 time units, published by Li & Liao (2019). Three bodies released from rest fall together, swing past each other and return to rest exactly where they started. It is unstable (largest Floquet multiplier 19591), so a small nudge makes it unravel over a few periods. The bodies pass within 0.000189 of each other at a top speed of 81.3, line up 28 times a period, and the computed loop closes to 1.0×10⁻²⁴.
