I.A.11

m₃ = 4

From Li, Jing & Liao (2018)

I.A.11 m₃ = 4 is a periodic orbit of the planar three-body problem: three masses in the ratio 1 : 1 : 4 that return to their starting positions and velocities every 86.304 time units, published by Li, Jing & Liao (2018). Class I.A orbits found with Liao’s clean numerical simulation method, for a third body of varying mass. It is linearly stable (largest Floquet multiplier 1.000), so a small nudge only makes it wobble. The bodies pass within 0.0000305 of each other at a top speed of 458, line up 246 times a period, and the computed loop closes to 1.1×10⁻²².
