I.A.23

m₃ = 4

From Li, Jing & Liao (2018)

I.A.23 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 159.85 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 0.0000247 of each other at a top speed of 509, line up 406 times a period, and the computed loop closes to 6.7×10⁻¹⁶.
