Figure-8 V.7.C

From Šuvakov & Dmitrašinović (2013). Sequences of orbits from the Belgrade three-body gallery.

Figure-8 V.7.C is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 35.043 time units, published by Šuvakov & Dmitrašinović (2013). Three equal masses chase each other along a single figure-eight curve, the most famous choreography. It is linearly stable (largest Floquet multiplier 1.000), so a small nudge only makes it wobble. The bodies pass within 0.36 of each other at a top speed of 1.77, line up 42 times a period, and the computed loop closes to 9.2×10⁻³⁰.
