I.A.32

m₃ = 0.75

From Li, Jing & Liao (2018)

I.A.32 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 80.177 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 unstable (largest Floquet multiplier 49.59), so a small nudge makes it unravel over a few periods. The bodies pass within 0.00155 of each other at a top speed of 27.1, line up 102 times a period, and the computed loop closes to 4.0×10⁻²⁵.
