Moth IVa.14.D

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

Moth IVa.14.D is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 97.363 time units, published by Šuvakov & Dmitrašinović (2013). Broad, fringed wings built from many overlapping passes. It is weakly unstable (largest Floquet multiplier 2.740), so a small nudge makes it unravel over a few periods. The bodies pass within 0.00394 of each other at a top speed of 15.9, line up 90 times a period, and the computed loop closes to 5.8×10⁻²⁶.
