Figure-8 V.17.H

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

Figure-8 V.17.H is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 88.673 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 0.408 of each other at a top speed of 1.64, line up 102 times a period, and the computed loop closes to 3.4×10⁻²⁹.
