II.C.11

From Li & Liao (2017)

II.C.11 is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 37.528 time units, published by Li & Liao (2017). The largest class in the atlas: hundreds of II.C orbits for seven mass ratios. It is unstable (largest Floquet multiplier 248.8), so a small nudge makes it unravel over a few periods. The bodies pass within 0.0000312 of each other at a top speed of 179, line up 48 times a period, and the computed loop closes to 2.9×10⁻²³.
