(395103) = 2009 RA8 -- Cometary Origin ?

 Is this a quasi-Hilda object?


Clone Generation

100 clones were generated in order to have the same orbital paameters and uncertainty as the nominal asteroid

Backward Simulation

This was performed using Mercury Integrator Package Version 6 - Bulirsch-Stoer N-body algorithm - 10^8 days in the past - output every 100 days

66% of the clones entered the solar system from a distance greater than 100 AU (i.e. from the point of view of the backward simulation they were "ejected")
