II.C.131

From Li & Liao (2017)

II.C.131 is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 110.52 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 0.00000104 of each other at a top speed of 981, line up 206 times a period, and the computed loop closes to 7.2×10⁻²¹.
