I.A.27

m₃ = 4

From Li, Jing & Liao (2018)

I.A.27 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 184.61 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 weakly unstable (largest Floquet multiplier 1.000), so a small nudge makes it unravel over a few periods. The bodies pass within 0.000019 of each other at a top speed of 581, line up 466 times a period, and the computed loop closes to 2.0×10⁻¹⁶.
