The capture of KBOs into long-lived apsidally anti-aligned orbital configurations occurs, with variable success, across a significant range of companion parameters ([[Fél nagytengely|semi-major axis]] ''a'' ~ 400–1500 AU, [[Excentricitás (csillagászat)|eccentricityexcentricitás]] ''e'' ~ 0.5–0.8). For their [[Görbeillesztés (matematika)|best-fitlegjobb illeszkedés]] nominal simulation, they selected ''a'' = 700 AU, ''e'' = 0.6, ''M'' = 10&nbsp;m_⊕ (meaning a body with ten times the mass of [[Föld|Earth]]), [[Inklináció|orbitalkeringési inclinationinklináció]] ''i'' = 30°, and initial argument of perihelion ω = 150° (compared to roughly 310° the average for the six analyzed TNOs).<ref name="TAJ201601"/>

The simulations showed that planetesimal swarms could be sculpted into collinear groups of spatially confined orbits by Planet Nine if it is substantially more massive than Earth and is on a highly eccentric orbit. Furthermore, the confined orbits would cluster in a configuration where the long axes of their orbits are anti-aligned with respect to Planet Nine, signalling that the dynamical mechanism at play is resonant in nature.<ref name="findPlanetIX">{{Sablon:Cite web|url = http://www.findplanetnine.com/2016/01/premonition.html|title = Search for Planet 9 – Premonition|date = January 19, 2016}}</ref> This mechanism, known as mean-motion resonance, prevents trapped [[Neptunuszon túli objektumok|trans-Neptunian objects]] from colliding with Planet Nine, and keeps them aligned.<ref name="CaltechJan2016">{{Sablon:Cite web|url = https://www.caltech.edu/news/caltech-researchers-find-evidence-real-ninth-planet-49523|title = Caltech Researchers Find Evidence of a Real Ninth Planet|date = January 20, 2016|accessdate = January 20, 2016|last = Fesenmaier|first = Kimm|publisher = California Institute of Technology}}</ref>
