Butterfly I.14.A

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

Butterfly I.14.A is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 61.323 time units, published by Šuvakov & Dmitrašinović (2013). Two wings of tight loops, with the bodies crossing through the centre at high speed. It is linearly stable (largest Floquet multiplier 1.000), so a small nudge only makes it wobble. The bodies pass within 0.00161 of each other at a top speed of 24.9, line up 94 times a period, and the computed loop closes to 3.6×10⁻²⁵.
