If the core-accretion model is correct, gas giants ought to be rare, Quinn argues. Yet since 1995, astronomers have found more than 100 extrasolar planets, and most of them are at least as massive as Jupiter.
This doesn't mean they're not rare.

The current techniques used to search for extra-solar planets are biased toward Jupiter (or larger) sized objects. We don't yet know how many smaller planets exist out there.
