II.C.113

From Li & Liao (2017)

II.C.113 is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 132.34 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 14.39), so a small nudge makes it unravel over a few periods. The bodies pass within 0.000279 of each other at a top speed of 59.9, line up 164 times a period, and the computed loop closes to 8.1×10⁻²⁵.
