Choreography SC.113

From Simó (2001)

Choreography SC.113 is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 11.87 time units, published by Simó (2001). Carles Simó’s catalogue of three-body choreographies with nonzero angular momentum, the curves that made choreographies famous. All unstable except the figure-eight. It is unstable (largest Floquet multiplier 10689), so a small nudge makes it unravel over a few periods. The bodies pass within 0.0441 of each other at a top speed of 5.27, line up 48 times a period, and the computed loop closes to 2.2×10⁻²⁷.
