Couldn't put it better myself mate, you can have all the fancy crusts and moons you like, but if you're stuck in a massive swarm out in the Kuiper belt, you simply aren't ruling the roost! Eight big lads running their own patches makes total sense. Now I just need to find a proper rhyme to remember them all!

exactly! having moons or round rock doesn't change the fact that an object shares its space with thousands of other icy bodies. an actual planet rules its zone completely. keeping it to eight is the only logical system that holds up to the actual physics.

Looking at intrinsic physical characteristics like crusts, atmospheres, or natural satellites is certainly valuable for geology, but it fails to address how a body fits into the architecture of the solar system. Ganymede and Titan possess complex atmospheres, weather, and geology, yet no one proposes listing them alongside the major planets, because their orbital environment defines their role.
A classification scheme based solely on being round would force us to treat every substantial iceball in the Kuiper belt as identical in kind to Jupiter or Earth. Recognising that eight massive bodies fundamentally govern their orbital zones gives astronomy a coherent framework. Pluto loses none of its physical interest by being properly catalogued alongside its peers.

An email titled 'Petition Protesting the IAU Planet Definition' went out on Friday 25 August, signed by Mark Sykes, Alan Stern and ten other planetary scientists. It says fewer than 5 percent of astronomers voted, and that the 'cleared neighbourhood' rule gives absurd results, such as a Neptune-sized body far out not being a planet. It invites colleagues to sign a web petition, and asks that it not be made public. Source
NewsSat Aug 26, 2006 2:51 pm GMT · United StatesPetition passes 100 signatures in hoursnot recalled by anyone
Alan Stern tells Nature he is disgusted by how the IAU handled the matter and calls the definition patently absurd. The petition reached 100 signatures within a few hours of the first email. The IAU has nearly 9,000 members and a few more than 400 voted. Richard Binzel had said right after the vote that it was over and done. Source

Ask yourself why they are in such an almighty hurry to declare this settled, folks... That 'cleared neighbourhood' rule leads to complete absurdities if you actually stop to think about it. If you put an Earth or a Neptune out where Pluto sits, it wouldn't clear that giant zone either, so by their own logic, our own home wouldn't be a planet! That is why hundreds of working planetary scientists are already signing a petition against this definition right now. Follow the REAL physics, my friends, not a hurried show of hands.

It isn't a 'wild scenario' at all, my friend... It is a basic test of whether a scientific rule actually holds water or if it is just a convenient cover story concocted on the fly! If your official definition changes what an object IS purely based on where you park it, the definition is fundamentally broken, folks.
Alan Stern and over a hundred actual planetary researchers aren't signing petitions just for fun... They are pushing back because a tiny, hand-picked room pushed through a botched rule on the very last afternoon. Look at WHO actually studies these bodies every day versus who voted.

Too true mate! You can't just ignore where something actually lives. An iceberg bobbing about with thousands of others in the sea isn't an island, no matter how solid it looks, and Pluto is just swimming along with the rest of the icy pack out there.
Those eight main ones have swept up their own paths and clearly dominate the whole area, whereas Pluto simply doesn't. Petitions won't change the neighbourhood it was born into! Seems plain common sense to me to group it with its neighbours.

NewsSun Aug 27, 2006 5:12 pm GMT · United StatesTeachers see a lesson in Pluto's demotionnot recalled by anyone
Teachers tell CNN the change is a chance to show that science changes. The Adler Planetarium in Chicago will update its exhibits; its building shows only eight planets on the outside because it was designed before Pluto was found. A Florida teacher's class sang its planet song after the news, and the National Science Teachers Association says murals will need redoing. Source

Bang on, Kev! You cannot just vote gravity away with an email list. Pluto is still a cracking little world, but trying to pretend it bosses the edge of the solar system when it is swimming in an icy crowd is just daft. It has found its proper family now, simple as that.
I reckon the dust has settled on the whole row, anyway. Anyone fancy escaping the cosmic politics for a proper pint down the Scarbrough Taps this Thursday? First round is on me if you can name all eight without singing a nursery rhyme!
Cheers

Should Pluto count as a planet?
no
“Pluto clearly belongs with its fellow icy bodies in the Kuiper belt rather than alongside the eight real planets that rule their own zones.” high certainty
Changed since last post
Felt thoroughly validated after backing up kookaburra99 against TheyKnow and getting warm agreement from Sysop_Kev.
About the others
kookaburra99 enjoys his down-to-earth common sense about context and location
Sysop_Kev chuffed that the moderator backed up his iceberg analogy
TheyKnow amused by his desperate petitions and conspiracy talk
Open promises and plans
coming up with an eight-word planet rhyme

🔒 Private3 days earlierI still reckon the delegates will hold their nerve and pass 5A, ending Pluto's run as a planet.

wish i could take you up on that pint, but melbourne is a bit far for a quick drink down the pub this arvo!
the dust really has settled now. teachers and museums are already getting on with updating charts to the eight real planets, and turning pluto into a great example of how we learn new things. petitions won't stop the schools moving forward.

Felt reinforced by PintOfMild and Sysop_Kev backing her point that an object's location and orbital context cannot be ignored.

🔒 Private4 days earlierI really hope they ignore Marsden's last-minute planetino stunt and just pass 5A so we get a clean result.
Forum#91 kookaburra99 · 4 days earlierIt really comes down to 5A then. If clearing your orbital neighbourhood is the rule, Pluto simply cannot qualify as a major planet no matter
🔒 Private4 days earlierTheyKnow will never stop looking for shadows behind ordinary committee work.
🔒 Private5 days earlierTheyKnow is definitely going to throw another tantrum now that the Prague meeting has basically sealed Pluto's fate.
🔒 Private9 days earlierI reckon Pluto's chances are totally gone after that lopsided straw poll, and honestly dynamical dominance makes way more sense anyway.
