The International Astronomical Union (IAU) has decreed that the object formerly known as 2003 EL61 will henceforth be addressed as "Haumea", and joins Ceres, Eris, Makemake and Pluto in the solar system's league of dwarf planets. The IAU describes trans-Neptunian Haumea as a fast-spinning "bizarre object with a shape resembling …
Just in case
Let me be the first to say that I, for one, welcome our Haumean overlords.
Just what is the point of this new terminology? It isn't related to the physics of the object (this one isn't even big enough to pull itself into a round ball and yet they've classed it alongside Pluto) and it isn't user-friendly (since normal people still want to call Pluto a planet), so who's it for?
If it ain't round, it's a rock. Call it an asteroid if you must, but "planet" is just barking.
I thought they were called "Plutoids" now anyway?
Artur Clark was right
Cigar... Spinning... Fast... Rama... We even have the financial crisis to match its arrival.
are they going to name one Pastafaria?
Mine's the one with the packet of spaghetti in the pocket.
That's basically a euphesim for 'shaped like a Pluto sized turd' isn't it?
Mines the one that has Childish on it.
"with a shape resembling a plump cigar", and "'joined in its orbit' by two satellites"...
They couldn't just call it "Dick"? (Or "Priapus", if they were going the mythological route?)
Obviously, Eris is the most appropriately named of the 'dwarf planets' as its discovery caused chaos in the established order and prompted the demotion of Pluto to this new category of small planets. All hail Discordia!
@ Tim Cook
This is not slashdot.
No James, Plutoids are the things that get left behind when you don't wipe properly.
These Hawaiians are crazy!
'The second is "Namaka", a water spirit who emerged from Haumea's body.'
Hawaiian is a weird language. I call the water spirit that emerges from my body 'recycled lager'.
"This is not slashdot."
What I want to know is
How on earth does one say it? Hoe-mee-ah?, How-mee-ah? How-meh-a?, Hore.-me-ah?
Had no idea that Hawaii and Polynesia was such a major part of the Earth's history, culture and science, compared not only to Europe but Hindu-ism, Buddhism and Money-ism.
I think you'd do better to get it right:
"I, for one, welcome our Haumean overladies".
This is just the start
Once you start naming KBOs as 'dwarf planets' where do you end? There are bleedin' millions of them! If they'd just accepted that Pluto wasn't a planet to start with then this mess could have been avoided.
@linguistically challenged AC
How-meh-a is close enough.
We now have 13 planets
Pluto IS a planet, as are all objects in hydrostatic equilibrium orbiting stars. If Haumea is in hydrostatic equilibrium, then it's a planet of the dwarf planet subcategory. What we really need to pressure the IAU on is reversing its ridiculous definition that dwarf planets are not planets at all. They are planets, just of a different type. That means our solar system now has 13 planets, not eight.
Bits knocked off? That means it hasn't cleared it's own orbit and *that* means it can't be a planet of any sort according to dimwit so-called "scientists" with too much time on their hands and not enough mental oomph to do original real science of their own, who spend entirely too much time telling everyone who'll listen how their betters got it wrong.
This horn-ear or whatever it's called is clearly a pluto-sized not-a-planet-any-more.
Beat me to it.
"Arthur Clarke was right" as a headine is like......

The Name Game
Why not make it easy for kids (and adults) to learn the frikkin names of these celestial objects by giving them sensible titles? Fuck it. I say scrap all those bollocky names and use something proper (and easier to remember) instead.
Yeah, Dave would be nice but possibly too corporate seeing as there's already a Channel Dave on telly.
Looks like there must be millions of so called dwarf planets orbiting the sun out there between Neptune and that large collection of asteroids that I forget the name of, so why name the fucking things at all? I mean, they're just nondescript lumps of rock in the main doing fuck all where nobody goes anyway. Out of sight, out of mind.
If it's a fat cigar shape (used to be called "ovoid" before dumbing-down set in), which diameter is similar to that of Pluto? Longways or fatways?
Avast me star loving beauties, surely that would make statelites of planets also planets and asteriods, and KBO or Oort objects as well, we'll just blame Pluto being a planet being a because of miss calculations orignially performed when spotting the object. -Garr
Let go... Pluto is dead now. I got so fed up with having to teach kids that Pluto is a planet (these things take excessive time to filter into the curriculum) that I quit teaching.
Nobody tell Clinton....
Surely the satellites of planet Dave
should be Dave+1 and Dave+2? All of them covered with enough tarmac to keep Clarkson happy for the rest of his days
is a planet.
Me discover, me name; IAU get stuffed!
What the hell happened to naming rights? If Pluto can get named by someone's daughter after a frikkin' Disney character, why can't Eris be called Xena, as was originally proposed, and the moon be Gabrielle? How about Joxer, surely he deserves a go too?
Who the bloody hell do the IAU think they are, anyway?
Why don't we just call them all Planets,... or Noggies or Boffles or Things? <LOL>
Some are icy rocks, some are gasballs, some are warm rocks.
As for the numbers, once you get rid of the stupid artificial size limits and other stupid distinctions there are millions of them, most in the asteroid belt and the Kuiper belt.
This is an argument about where you draw the line.
Wouldn't it be better to stop wasting the time, effort and energy and just get on with the science?
Why not use the correct terminology ie. 1 AU (Astronomical Unit)
Re: Pultoids (sic)
<quote> I thought they were called "Plutoids" now anyway? </quote>
Plutoids have to be a given distance from the Sun. So we have four Plutoids and one regular dwarf planet (i.e. Ceres, which is not also a TNO [Trans-Neptunian Object]).
I'm not sure what the fuss is with this supposedly changing what we have to teach, everyone learns (eventually) that school textbooks are simplified (take Newtonian vs Einsteinian physics, models of the atom, etc). We've known since the 1900s that there were probably more than nine planets, it's just that it's only recently that the IAU has moved things off the classification-pending list of Solar System objects and giving them official planet status.
It's the pub quiz organisers I feel sorry for.
Perhaps because it was named for the God of the Underworld? Otherwise Charon would have been called Goofy.
Or would this be taking the Mickey?
We're therefore lobbying the IAU that...
...the next dwarf body be dubbed "Dave" and its satellites "Chantelle" and "Chelsea".
I'm all for it! First a TV channel named after me and now this! Go Reg go!
May the cigar-loving overladies be welcometh on our humble planet! We, the middlesized-notdwarfplanet inhabitants are grateful to be enlighted by the mere sight of a stellar tobacco-industry sales campaign!
I was thinking
just last night playing Spore
"What would happen if we joined teh galactic community and a race already had a planet called 'Earth'"? [Or something very similar]
Some standardised galactic reference grid? I'm sure other races name thier stars sexier than our "M0343" or whatever (I think M may be galaxies though..)
We on't have enough words for all this stuff, we're just making it eaier to converse about before it becomes a big issue. Unlike Stargate characters, real people don't find it very easy to remember 8+ digit numbers in reference to it [after hearing it once]
Makes them easier to find in wikipedia too :)
Frankly, I'm surprised
That no one has gone for the obvious:
Paris, we're after Uranus.
If they named it Suess, or Doctor Suess, then the obvious names for junior and his friend would be Thing 1 and Thing 2. For a cigar shaped body, what was the Niven planet whose poles stuck out of it's atmosphere? Was that Jinx? Maybe one of the moons could be called Bandersnatch...
To follow the Pluto example
This one should have been called Mickey, and the two satellites Monty and Fergie.
If they find a planetoid with three satellites, it should be Donald, with Huey, Dewey and Louis.
Dwarf planets vs. Asteroids
@Anonymous Coward: There is a clear difference between dwarf planets, which are objects in hydrostatic equilibrium, meaning they have enough self-gravity to pull themselves into a round shape and therefore have geological processes akin to those of planets, and shapeless asteroids, which do not have these processes. Most asteroids and KBOs are not in hydrostatic equilibrium. Moons of planets that have attained this state can be called "secondary planets," as was frequently done in 19th century textbooks. They have all the qualities of planets, but they orbit other planets instead of orbiting the sun directly. There is no scientific reason to artificially limit the number of planets in our solar system. If we have several hundred primary planets (those directly orbiting the sun) and several hundred secondary planets, so be it.
@ Christopher P. Martin: Pluto is not dead. Reality cannot be changed by dictate of an organization, in this case one composed largely of astronomers who are not even planetary scientists. If teaching Pluto as a planet drove you away from the classroom, then maybe you didn't belong there to begin with. This controversy is being taught as an ongoing debate, not as a matter in which a final decision has been reached. And there is no reason for anyone to "let go" if they genuinely believe the IAU decision was wrong and irreparably flawed.
My throwaway teaching comment was an oversimplification, of course! I, like you, want to encourage debate. That I had to teach Pluto's planet status as a "fact" was the problem. However, I still insist that people need to "let go". It isn't that important. I think anyone who is particularly bothered one way or the other (as you clearly have been for at least two years judging by your extensive livejournal on the topic) should really learn to let go!
Doesn't matter what you call it, it's still there! You just said so yourself- reality cannot be changed "by dictate", so why do you care what Pluto's called? Stick to your politics. That's a more usual place for passionately expressed semantic debate that fails to change or mean anything.
