I.B.78

m₃ = 0.5

From Li & Liao (2017)

I.B.78 m₃ = 0.5 is a periodic orbit of the planar three-body problem: three masses in the ratio 1 : 1 : 0.5 that return to their starting positions and velocities every 82.059 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 0.0000942 of each other at a top speed of 119, line up 160 times a period, and the computed loop closes to 9.1×10⁻¹⁷.
