II.C.208

From Li & Liao (2017)

II.C.208 is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 100.32 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 23.66), so a small nudge makes it unravel over a few periods. The bodies pass within 0.0347 of each other at a top speed of 5.38, line up 94 times a period, and the computed loop closes to 2.7×10⁻²⁷.
