I.B.45

m₃ = 2

From Li & Liao (2017)

I.B.45 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 121.17 time units, published by Li & Liao (2017). Class I.B orbits, for equal and unequal masses. It is linearly stable (largest Floquet multiplier 1.000), so a small nudge only makes it wobble. The bodies pass within 0.000151 of each other at a top speed of 133, line up 316 times a period, and the computed loop closes to 1.1×10⁻²⁴.
