II.B.10

From Li, Jing & Liao (2018)

II.B.10 is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 189.77 time units, published by Li, Jing & Liao (2018). Class II.B orbits, mostly long-period. It is unstable (largest Floquet multiplier 139.3), so a small nudge makes it unravel over a few periods. The bodies pass within 0.000386 of each other at a top speed of 50.9, line up 248 times a period, and the computed loop closes to 1.4×10⁻²⁴.
