Choreography SC.150

From Simó (2001)

Choreography SC.150 is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 13.135 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 25536), so a small nudge makes it unravel over a few periods. The bodies pass within 0.0512 of each other at a top speed of 5.04, line up 54 times a period, and the computed loop closes to 5.3×10⁻²⁸.
