Family NF.68

From Hristov, Hristova, Puzynin, Puzynina, Sharipov & Tukhliev (2022)

Family NF.68 is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 57.104 time units, published by Hristov, Hristova, Puzynin, Puzynina, Sharipov & Tukhliev (2022). Orbits from topological families that no earlier catalogue contained; all of them unstable. It is unstable (largest Floquet multiplier 401), so a small nudge makes it unravel over a few periods. The bodies pass within 0.000942 of each other at a top speed of 32.6, line up 72 times a period, and the computed loop closes to 6.9×10⁻²⁵.
