II.C.144

From Li & Liao (2017)

II.C.144 is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 184.44 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 3.062), so a small nudge makes it unravel over a few periods. The bodies pass within 0.000483 of each other at a top speed of 45.5, line up 198 times a period, and the computed loop closes to 5.2×10⁻²⁵.
