Abstract
Orbital computation of 3,372 real near-Earth asteroids (NEAs) population was conducted and their evolution was recorded every 1,000 years for the next 5 Megayears (Myr). This study is aimed to detect asteroids in 1:1 mean-motion resonance (MMR) with planets. In order to achieve our goal, we employed N-body numerical simulation with the use of Swift-RMVS (Regularized Mixed-Variable Symplectic) integrator. We found that NEAs population could have evolved into asteroids in a co-orbital state with Terrestrial planets (Mercury to Mars). In order to detect this co-orbital condition, the time-series motif discovery algorithm was applied against asteroids‘ orbital element. The predicted motif location and duration of 1:1 MMR were then compared with one of the standard software in astronomy that showed conformity of results greater than 80%.
