I.A.58

m₃ = 2

From Li, Jing & Liao (2018)

I.A.58 m₃ = 2 is a periodic orbit of the planar three-body problem: three masses in the ratio 1 : 1 : 2 that return to their starting positions and velocities every 177.78 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 1.011), so a small nudge only makes it wobble. The bodies pass within 0.0000101 of each other at a top speed of 515, line up 454 times a period, and the computed loop closes to 8.5×10⁻²¹.
