II.C.210

From Li & Liao (2017)

II.C.210 is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 106.28 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 137.6), so a small nudge makes it unravel over a few periods. The bodies pass within 0.0222 of each other at a top speed of 6.71, line up 100 times a period, and the computed loop closes to 1.7×10⁻²⁷.
