How are these percentages derived?

Which brings to mind another interesting possibility.
Wth the recent discoveries of Jupiter-class planets surrounding other stars
and hypothesized terrestrial companions, what would an extra-solar meteorite
"look like?" How would we recognize it as such? Has a meteorite been found
that is so different (possibly unique) that it might be of extra-solar origin?
