Choreography SC.152

From Simó (2001)

Choreography SC.152 is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 13.162 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 32933), so a small nudge makes it unravel over a few periods. The bodies pass within 0.0464 of each other at a top speed of 5.15, line up 54 times a period, and the computed loop closes to 6.7×10⁻²⁹.
