Choreography SC.325

From Simó (2001)

Choreography SC.325 is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 16.583 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 11736), so a small nudge makes it unravel over a few periods. The bodies pass within 0.0313 of each other at a top speed of 6.35, line up 78 times a period, and the computed loop closes to 6.1×10⁻²⁶.
