II.C.194

From Li & Liao (2017)

II.C.194 is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 75.105 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 310.3), so a small nudge makes it unravel over a few periods. The bodies pass within 0.00106 of each other at a top speed of 30.7, line up 52 times a period, and the computed loop closes to 3.9×10⁻²⁵.
