Pluto is out!

The ACLU has nothing else better to do than to make peoples lives different.

The only thing that doesn't change about the ACLU is change...

That was Bluto.

No i'm talking about Sailor Pluto from Sailor Moon.

this is stupid
a asteroid is now a planet, while pluto bigger than its moon(now a planet) is not classed as a planet

Which asteroid is now a planet?

I think you're getting confused between the two definitions. One proposed definition, which included Pluto as a planet, would also class Charon, Ceres (an asteroid), 2003UB313 and probably Quaoar and Sedna as planets. The actual accepted definition doesn't include any of them as planets, so there are EIGHT planets in the Solar System.


Incidentally, Charon isn't Pluto's moon. They orbit around a point between them which isn't contained within either of them, so they are a binary pair, rather than a planet/moon couplet.

But Pluto was my favorite planet, all small and distant and alone...poor poor pluto.

Don't worry, it's not going anywhere

I guess www.nineplanets.org should really get a new domain name Atleast they've updated their front page, albeit rather unceremoniously...

 

[Metar]

I saw this on the local news a while ago. One less planet for kids to learn about.

Yeah. My brother won't be able to use my school-software that I used, since Pluto's no longer on the list.

Pluto's always been an outsider... Wasn't he actually discovered at first through mathematical calculations, and only then sighted? I remmember reading something about a guy who discovered changes in Uranus' (know that Futurama chapter, with the Urektum?) course, which led to the discovery of that Disney Dog.

 

[Danoff]

aw......that cuts out people saying ALIENS are from there.......oh well....

What? I think you're confused. Pluto still exists. The board didn't decide that pluto doesn't exist. You can still claim aliens are from there even if it isn't a planet.

Pluto is and always has been a Kuiper Belt Object and nothing more. We're just finally realizing it. Astronomy is a science, and as such needs to have clear definitions for categories of objects that make sense. Any non-arbitrary definition that included Pluto as a planet would either have to include additional bodies as planets or would kick out Mercury (and possibly add Titan).

This decision has been a long time coming and was pressed into importance by the fact that we're getting better and better at finding more objects (in our solar system and others).

Citizens of HD 69630 d (illustrated below) recently voted to upgrade Earth to a planet after classifying us as mere detritus for years, until their SETI program got underway and they discovered our old radio and television broadcasts... we haven't detected any signals from them because they have developed technology capable of masking any electromagnetic radiation broadcasts (i.e. to avoid the 'bird's nest effect'), but they are capable of tuning in to our broadcasts, which have been winging their way through space since they were first broadcast here.... Infact, the good people of planet HD 69630 d (some 41 light years away), have just recently enjoyed watching The Beatles performing 'Help!' on the Ed Sullivan show, and in a few months time will be treated to the first ever showing of 'A Charlie Brown Christmas'...

So who wants to tell them that two of the Beetles are dead, or do we just assume Paul and Ringo will be likely be dead in another 41 years?

 

[Touring Mars]

Well, it's something - but Pluto is still a planet, apparently... albeit a newly classified "Dwarf Planet" alongside Eris and Ceres...

​

 

[DQuaN]

So what is Charon?

 

[Touring Mars]

At the moment it's categorised simply as a Plutino according to Prof. Wiki of Wikipedia University - it's possibly a dwarf planet too, but at the moment the application is in post...

... there goes my catchy phrase thingy that I made up in 2nd grade. Why talk about pickles and pie when you can talk about planets?

[viperpilot]

nice catchy phrases you've got here........ *gg* made me laugh!

i'm very sad that pluto isn't a planet anymore, they always knock the tiniest off!

Looks like Earth is inside the Corona of the Sun! AAAAAHHHH!!!

If saturn tilted just a little, it's rings would go through Jupiter. Now that would be a sight to see.

 

[Danny]

Don't joke about that danoff, they'd also go through Uranus.

Or maybe some of the ice, rock and dust that form the ring would move to Uranus' field of gravity.

Uranus would have a ring.

Doesn't Uranus (Oh sorry, the scientists in the year 3000 re-named it "Urektum", but that's Futurama) already have a blue ring?

 

[Touring Mars]

Yes, Uranus does have a ring - or, more accurately, a ring system.
