Pluto Demoted!

[shapu]

There are no plutons anymore...it's going to qualify for "Dwarf Planet" status.

Here's how it works:
Pluto is not a planet because until today, scientists have never had a definition of what a planet was (the Greeks said it was something that moved relative to the stars, but then, they could only see Saturn in the night sky).

So now there's a definition of a planet: It's big enough to have the gravity to squeeze it into a round shape, it orbits the sun and not another object, and it has a cleared orbital path (meaning that it won't cross the path of something bigger than itself on its trips around the sun).

Pluto doesn't fit the third criteria, because its orbit crosses Neptune's orbit.

So now we have eight planets, without pizza, and several dwarf planets. Pluto, Xena, and Ceres (probably) will become dwarf planets, and then there will be a solar-system object classification.

Everything I know (about the planets) is now a lie.

Forget that, Sailor Pluto is now a lie.

That's fine, I had a thing for Sailor Mercury anyway.

Oh no! I forgot about that. She was my favourite.

Sailor Moon is my favorite from Sailor Moon but I don't see Toei Animation doing away with Sailor Pluto now despite the recent news involved the planet Pluto as she is part of Sailor Moon history.

Back to the planet Pluto. They need to decide one way or the other as we have be hearing that Pluto is not a planet then we hear that it is a planet again and then we hear that it isn't a planet again. (Then we will hear that is a planet again) It is so confusing at the moment as we are being told different things about Pluto both from the it is a planet side as well as from the isn't a planet side.

Agreed. I just read an article from MSN (link) about the whole issue which states that only 424 out of 10,000 astronomers were able to vote on it. It'll probably be going back and forth for a long while.

the took off pluto but we have 12 planets now, dont know if someones already posted this because i just checked in, theres one after mars and 2 after pluto. and one somewhere else.. *just checked his math*

One teacher at my high school said that at one point they were using a textbook in 1985 that said "one day man will land on the moon" (no joke.)

Which would've meant the book was 16 years old. .. Or you messed up the date.

To be honest, replacing every textbook because of a inevitable progression-of-though is stupid. Any good teacher would be able to work around the outdated information, and any good student would ignore the innacuracy instead of blurting out "But sir, it says here Pluto is one 'the nine planets'! But it isn't!"

speaking of books.. i have a math book thats as old as my little brother..

Before we got new old (from 1993) textbooks, ours said that too.

No, no, no, not quite. They were planning to have twelve planets; which was the basic jist of the proposal that demoted Pluto, the other three planned planets were Ceres, (an astroid by Mars) Charon, (Pluto's moon) and Xena (somewhere behind Pluto). But they are all too small, so they're dwarf planets too. Except Charon. It's still a moon.

My very educated mother just served us nachoes? Noodles? Nectarines? Oh, but they aren't the same as nine pizzas. ;_;

[Asthaloth]

Errr.
The Textbooks won't be changed.
If they werent when it was realised the theory of Gravity is wrong they wont for this.

[DiscordantNote]

You guys are forgetting Sedna, another large, spherical object beyond Pluto. That's in the running too.

The deal with Charon is that, if it was called a planet, it and Pluto would be referred to as a binary planetary system much like two stars orbiting each other or a common center of gravity are called. Thing is, that might have meant Earth and our moon could've been called the same thing.

i heard a rumour that most astromeners think that pluto isnt a planet, but as its the only one that has been named by an american the americans want to keep it as a planet

(apologies for terrible spelling)

No worries with that. Pluto and Charon rotate around a point that is not within the bodies of either - that is, they rotate around a point in open space. The moon rotates around a point pretty close to the center of the earth.

[NeoPet_online]

I say we call an unnamed planet Adex, and just get it over with. Lol JK! But I am going to miss pluto and his sully little antics.

Lol I loved that do....

Oh wait... Um... It's a shame the planet got demoted....

Oh no! I forgot about that. She was my favourite.

She'll just be remastered as a chibi for blu-ray.
