II.C.262

From Li & Liao (2017)

II.C.262 is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 181.46 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 1.008), so a small nudge only makes it wobble. The bodies pass within 0.0000187 of each other at a top speed of 231, line up 222 times a period, and the computed loop closes to 3.4×10⁻¹⁶.
