II.C.141

From Li & Liao (2017)

II.C.141 is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 195.17 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 59.7), so a small nudge makes it unravel over a few periods. The bodies pass within 0.001 of each other at a top speed of 31.6, line up 206 times a period, and the computed loop closes to 7.8×10⁻²⁵.
