II.C.149

From Li & Liao (2017)

II.C.149 is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 159.05 time units, published by Li & Liao (2017). The largest class in the atlas: hundreds of II.C orbits for seven mass ratios. It is linearly stable (largest Floquet multiplier 1.000), so a small nudge only makes it wobble. The bodies pass within 0.00000252 of each other at a top speed of 63, line up 230 times a period, and the computed loop closes to 6.7×10⁻²⁰.
