II.C.156

From Li & Liao (2017)

II.C.156 is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 145.38 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 0.0000496 of each other at a top speed of 142, line up 250 times a period, and the computed loop closes to 1.8×10⁻²³.
