Assuming it's possible for an asteroid or comet to enter an orbit that would 
fling it out of the solarsystem, it seems logical that material from neighboring 
systems could, albeit rarely, enter ours.

If such an extrasolar piece landed here on earth would it then be possible (by 
analyzing for example it's composition or age) to prove that it was from out of 
town?
Or to refrase the question: Does all local material have a "fingerprint"?
