II.C.211

From Li & Liao (2017)

II.C.211 is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 109.63 time units, published by Li & Liao (2017). The largest class in the atlas: hundreds of II.C orbits for seven mass ratios. It is unstable (largest Floquet multiplier 358.7), so a small nudge makes it unravel over a few periods. The bodies pass within 0.0285 of each other at a top speed of 5.93, line up 100 times a period, and the computed loop closes to 2.2×10⁻²⁶.
