Butterfly IVb.14.B

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

Butterfly IVb.14.B is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 55.557 time units, published by Šuvakov & Dmitrašinović (2013). A second butterfly sequence with a different topology from class I. It is linearly stable (largest Floquet multiplier 1.000), so a small nudge only makes it wobble. The bodies pass within 0.000391 of each other at a top speed of 50.5, line up 100 times a period, and the computed loop closes to 8.5×10⁻²⁵.
