Broucke region HS.434

From Hristov, Hristova & Tanikawa (2026)

Broucke region HS.434 is a periodic orbit of the planar three-body problem: three equal masses that return to their starting positions and velocities every 300.59 time units, published by Hristov, Hristova & Tanikawa (2026). Stable orbits related to Broucke’s isosceles orbit, with one body swinging through the other two. It is linearly stable (largest Floquet multiplier 1.000), so a small nudge only makes it wobble. The bodies pass within 0.00000156 of each other at a top speed of 801, line up 360 times a period, and the computed loop closes to 9.4×10⁻²¹.
