I.A.43

m₃ = 0.75

From Li, Jing & Liao (2018)

I.A.43 m₃ = 0.75 is a periodic orbit of the planar three-body problem: three masses in the ratio 1 : 1 : 0.75 that return to their starting positions and velocities every 96.598 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 0.000167 of each other at a top speed of 82.7, line up 142 times a period, and the computed loop closes to 5.3×10⁻²⁴.
