2008 LC18: A potentially unstable Neptune Trojan

Horner, J; Lykawka, P S; Bannister, Michele; Francis, Paul


The recent discovery of the first Neptune Trojan at the planet's trailing (L5) Lagrange point, 2008 LC18, offers an opportunity to confirm the formation mechanism of a member of this important tracer population for the Solar system's dynamical history. We tested the stability of 2008 LC18's orbit through a detailed dynamical study, using test particles spread across the ±3σ range of orbital uncertainties in a,e,i and Ω. This showed that the wide uncertainties of the published orbit span regions...[Show more]
