By the way, the article is wrong when it say Jupiter hasn't cleared its orbit of asteroids. Most asteroids have been herded into the asteroid belt by Jupiter, which is just outside Mars's orbit. The Trojan asteroids have been herded into clumps that are always at a distance from Jupiter. The only asteroids which Jupiter occasionally encounters have unstable orbits, not stable ones.
And there are those that say Neptune hasn't cleared its orbit because Pluto's orbit crosses it at one point. But Pluto has been forced by Neptune into a 3:2 orbital resonance where it never comes close to Neptune. So again, Neptune has cleared its orbit.

The problem is the IAU 2006 requirement of clearing an orbit is extremely vague for scientific purposes. But I would expect nothing else from such a hasty and heavy handed effort.
