Re: 2001 RX14

What is the aphelion distance for this object? --- Said position exceeds the scope of JPL's 'Orbit Simulator'. Their 1/1/2200 time horizon shows the comet at point ~200 AUs distant. Yet, based upon the contour of the (truncated) ellipse the object is then yet _very_ far from apogee...

Is it possible 2001 RX14 is not properly part of this solar system (to wit: could it be a bit of interstellar 'flotsam' having been 'snared' by, but ascending with sufficient velocity to escape, Sol's gravitation? --- *OR* does the Kuiper Belt extend further that I imagine?

Apologies for the fundamental nature of this question - Guess I'm an amateur amateur ;)

Advance thanks & Best regards
