SN.14

From Šuvakov (2026). Thirteen equal-mass orbits with angular momentum from Milovan Šuvakov’s own searches, shared with this atlas.

SN.14 is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 9.4143 time units. Thirteen equal-mass orbits with angular momentum from Milovan Šuvakov’s own searches, shared with this atlas in September 2026. Seven are the figure-eight carried to nonzero angular momentum, its 1/5 to 2/3 resonances, all linearly stable; four lie on a branch that ends, at zero angular momentum, in Broucke’s isosceles collision orbit; two branch off Broucke’s A family. Numbered as in his file. It is unstable (largest Floquet multiplier 1772), so a small nudge makes it unravel over a few periods. The bodies pass within 0.23 of each other at a top speed of 2.26, line up 18 times a period, and the computed loop closes to 1.0×10⁻²⁷.
