I agree that Pluto is a member of the Kuiper Belt, which means that it was once a comet. But then, out of nowhere, a meteorite or another comet smashes into Pluto, knocking it plain out of orbit. Pieces from the impact form back, giving Pluto a spherical look. Other pieces form Pluto's neighbor moon, Charon.

Also, I heard that during it's 20 earth years in front of Nuptune, it had an atmosphere. That atmosphere development was likley pernament, so it probably still has it. I've seen blurry, close up pictures of Pluto, and it looks like it has an atmosphere. Also during those years, if they weren't formed in the impact, two objects must have got caught in the orbit of the tiniest planet of the Solar System. Those were Pluto's secondary moons, Hydra and Nix.

The other thing is, New Horizons was already on the way, and it was unfair to kick Pluto out of the planet club when the first probe to get there was on the way. So what those IAU geeks say are fat-out lies. WAIT 'TILL NEW HORIZONS HAS EVIDENCE, THEN YOU CAN TELL WHETHER PLUTO IS A PLANET OR NOT. So what those people say isn't official. Those 2,500 scientists came there for nothing. Pluto IS a planet, and it always will be. Oh, sure, it has a bad orbit, and passed in front of Neptune for 20 years, but like I said in the beginning, just because the ninth planet has a bad orbit, doesn't mean it's not a planet. So it's official. PLUTO IS A PLANET.

What does it have to clear?

Will Pluto ever be re-instated as a planet?
