Choreography NC.88

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

Choreography NC.88 is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 261.94 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 580120171), so a small nudge makes it unravel over a few periods. The bodies pass within 0.0000144 of each other at a top speed of 263, line up 168 times a period, and the computed loop closes to 5.6×10⁻¹⁷.
