Moth IVa.15.B

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

Moth IVa.15.B is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 98.649 time units, published by Šuvakov & Dmitrašinović (2013). Broad, fringed wings built from many overlapping passes. It is linearly stable (largest Floquet multiplier 1.000), so a small nudge only makes it wobble. The bodies pass within 0.00275 of each other at a top speed of 19.1, line up 96 times a period, and the computed loop closes to 5.6×10⁻²⁶.
