I believe it's classified as a dwarf planet. In this sense, it is and it isn't. On that note, should Eris also be reclassified? Wouldn't that mean we now have ten planets in the solar system? What about Ceres?
If it was entirely up to me, then any natural-occurring spherical body in a circular orbit around the Sun would be classified as a planet. But that's just me.
I suppose it's all semantics at this point. Maybe we should just call them "Those big ball things what are in the sky or something". Works for me. I like simplification.


Changing from a handy word like "planet" to "T.B.B.T.W.A.I.T.S's" would be a complication, and not a simplification.

Americans love Pluto. The cartoon dog above was named after it because Disney got his start about the same time it was discovered.

Love Pluto because it was discovered by an American, and probably also because,like American itself, Pluto's discovery happened because of a mistake when someone was trying to discover something else. Lol!

So Americans have a vested interest in keeping Pluto high status.

You could go by Fnord's criteria. The trouble is that if you did you would have to promote objects like the asteroid Ceres up to planet status. Ceres is only 480 miles wide (but it has a circular orbit around the Sun, and is spherical shaped).

To me, unscientifically speaking, a planet needs to have an atmosphere to be a planet. Pluto does have a thin atmosphere of mainly nitrogen. But the again I see that Ceres has a tenuous water vapor atmosphere.

I'm waiting for Disneyland Pluto. It'll probably be someone among my distant descendants who actually gets to visit, though.

Yes, and I see no problem with that.

I can see the contentedness in parsing the orbs into major and minor status planets, after all. it is a useful means of reducing the cerebral load of keeping track of them all.

I like Pluto whether it's large or small, it's simply within the realm of our universe, as I feel there are so many things out there, there is no telling what new terms will be created.

The bible says there are nine planets, so that's what science needs to stick with.

I feel there could a multitude of planets within the Oort cloud though, at this time our technology and the extreme distance makes detecting them easily. Yes, several exo-planets have been found but, those were not easy found either so, I don't go by what some book says, end quote.

Jacobite English, to be technical about it. :-)

They can claims it's a gateway to an alternate dimension where humans all look like pigs and think humans in our world look ugly for all I care. :roll:

It all boils down to this: Define PLANET. Pluto was stripped of this status because it lacks sufficient gravity to clear its orbit of all debris...but in order to clear that orbit of all debris, Jupiter would lack enough gravity, in fact you would need a body FOUR TIMES as massive as Jupiter to do it.

I don't think Pluto should be considered a planet because of its composition--its essentially the head of a comet.
