II.C.114

From Li & Liao (2017)

II.C.114 is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 196.24 time units, published by Li & Liao (2017). The largest class in the atlas: hundreds of II.C orbits for seven mass ratios. It is weakly unstable (largest Floquet multiplier 2.488), so a small nudge makes it unravel over a few periods. The bodies pass within 0.00105 of each other at a top speed of 31, line up 160 times a period, and the computed loop closes to 1.1×10⁻²⁵.
