Choreography NC.113

From Hristov, Hristova, Puzynin, Puzynina, Sharipov & Tukhliev (2024)

Choreography NC.113 is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 161.57 time units, published by Hristov, Hristova, Puzynin, Puzynina, Sharipov & Tukhliev (2024). Choreographies whose knot is not a power of the figure-eight’s: three bodies on one closed curve with a topology of its own. Computed to 180 digits; all unstable. It is unstable (largest Floquet multiplier 15907924854), so a small nudge makes it unravel over a few periods. The bodies pass within 0.00055 of each other at a top speed of 42.7, line up 186 times a period, and the computed loop closes to 1.4×10⁻¹⁹.
