I was over at cnn.com and I glanced at this and ended up using it in another thread, and now feel that it deserves its own thread.

http://edition.cnn.com/2009/TECH/space/08/24/pluto.dwarf.planet/index.html

My stance is that you can pry my 9 planet solar system chart from my cold dead fingers.

First they had Cookie Monster recommend eating vegetables, then they took away the only planet named after a dog. Is there no shame?!

For more scientific postulatings, please respond below.

I'll not vote as I don't want to pass judgment yet.

When the spaceship gets there in 2015 they will find out hopefully if it is basically dead ice or whether or not it has a dynamic environment. I say if it's just a chunk of dirty ice - take away ' planet status.' If not, bring back the planet status and offer a sincere apology!

'Me want veggies!!!'

Nah, that's just not the same...

'Me want COOOOOOOKIIIIEEEEEEEEEE'

That hits the spot.

Considering Pluto is the same category as Earth -- the category of planets -- is no more ridiculous than considering Earth to be in the same category as Jupiter.

If we want to get rid of the categorization entirely, that's one thing. If we're going to keep saying the solar system has eight planets and lump Jupiter and Earth together, we might as well keep saying it has nine for tradition's sake.

Cookie Monster eating anything except cookies is also an abomination.

Firstly, I'm in favor of classifying as a planet anything that's spherical and orbits a star directly (regardless of its size. A dwarf planet is just a sub-category of planet, same as gas giant). This will increase the number of planets in the Solar System to at least 12, I think - but there are probably many more, particularly in Pluto's region.

Secondly, in the case of Pluto and its 'satellite', Charon, I'm in favor of them being classified as a double-planet system (two planets both tidally-locked to one another, in contrast to the normal planet/satelite scenario).

Those pale in comparison to taking away Mr. Potato Head's pipe. Get your priorities straight.

But yes, I mourned for months when we lost Pluto as a planet. Can't really be resuscitated?

In 1975, psychiatrists voted to remove Homosexuality as a diagnosis from the DSM. If enough of us vote to do so, can't we make Pluto a planet again?

Of course Pluto is not a planet.

It doesn't have a regular orbit and there are many other objects close to its size in the same area. Therefore it has not cleared its area, therefore it is not a planet. It doesn't fit into the current classification of what a planet is.

Yes, it's a planet. The definition should be orbits a star + has hydrostatic equilibrium (=enough mass to retain a spherical shape). That makes Ceres a planet as well.

I tend to agree that 'cleaning it's neighborhood' is key to being classified as a planet. As of now Pluto-Charon haven't really done that. It's a part of the Kuiper belt, and nothing further.

Yeah, I was annoyed when it was pulled from the pantheon of planets, but science marches on...
