I run a simulation using the nominal orbital parameters read from JPL (Horizons Web Interface).
Uncertainty condition code: 0
Algorithm: Bulirsch-Stoer (conservative systems)
Integration start epoch: 2458000.5000000 days
Integration stop epoch: -10^8 days
Output interval: 100.000 days
Output precision: medium
Initial timestep: 0.100 days
Accuracy parameter: 1.0000E-12
Ejection distance: 1.0000E+02 AU
This plot has been made using the R-package.
This seems to show that this asteroid was previously a TNO.
