II.C.272

From Li & Liao (2017)

II.C.272 is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 170.71 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 0.0000117 of each other at a top speed of 293, line up 292 times a period, and the computed loop closes to 4.2×10⁻²².
