II.C.241

From Li & Liao (2017)

II.C.241 is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 157.23 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 374.5), so a small nudge makes it unravel over a few periods. The bodies pass within 0.00804 of each other at a top speed of 11.2, line up 156 times a period, and the computed loop closes to 5.0×10⁻²⁵.
