I.A.34

m₃ = 0.75

From Li, Jing & Liao (2018)

I.A.34 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 91.57 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 19.77), so a small nudge makes it unravel over a few periods. The bodies pass within 0.0015 of each other at a top speed of 27.6, line up 106 times a period, and the computed loop closes to 7.0×10⁻²⁵.
