So now there are 12 planets....

[Thraxen]

:thumbsdown: to the people asking, "Why does it matter?".

Anyway, it looks like they are breaking the planets down into different classifications, with the very small ones being called "plutons".

ok.. ceres and xena i've heard of. Where did this 12th planet come from?!

Charon is a moon of Pluto and under the new definition would be consider a planet, or "plutons"

wtf?! how does a very small moon of a very small planet get to be a planet? yet Earth/ saturn/jupiter's moons arent?

Charon is about the same size as Pluto, so it's part of a double planet rather than a moon.

From what I gather, they are a binary ststem, also. Meaning neither orbits each other, instead both orbit a barycenter in space between them. Thus, neither is a moon.

pluto isn't a planet

That's the way all orbits are. It's impossible for any planet or star to not wobble from its satellite's mass.

From what I've heard the reason that the Moon is still a moon but Charon is a planet has to do with the location of the center of mass of the planet-moon system (relative size.) While the Moon is indeed much larger than Pluto the center of mass of the Earth and Moon combined still lies below the Earth's surface due to the Earth's larger mass relative to the Moon. Pluto and Charon are much closer in size to each other and thus the center of mass of their system is relatively farther away from either body.

I've seen some chix who could be classified as planets under that definition.

Pic for a clearer demonstration. I want to orbit around those babies.

Grabrielle has hotter than Xena, but she was made to look like an ordinary sidekick.

 

[EKKC]

cant they name the new planets Tatooine, Death Star or something cool

 

[SagaLore]

Perhaps the true definition of a planet should be any astronomical body of mass capable of supporting life with an atmosphere (not necessarily meaning an atmosphere exists, just that the amount of gravity could make it possible).

The rest of them are just solar masses.

 

[preslove]

They need to just make an arbitrary definition using the mass of the object to call it a planet. Anything smaller than mercury is not a planet.

Mars has a thin but substantial atmosphere. However Mercury has almost nothing.

i want to name a planet...name it Syrch!

hot redhead ftw!

although i think i saw some shots of her in later seasons where her hair was cut really short and dyed like platinum blonde.

Some are just frozen masses of gas on some rock.

I think in order to be called a "planet," a celestial object must have a significant gravitional field and contain an atmosphere. Of course the scientists are debating that now.

mars doesn't really have an atmosphere

Uh yeah it does..
It's made up of carbon dioxide.
You must be thinking of mercury.

 

[KDOG]

I don't know why they just don't use Pluto as the minimum standard for a planet. Any bigger - planet. Any smaller - just a rock.

But what about the converse, Jupitor and Saturn are pretty much all atmosphere. They may have a rocky core, we don't know, but if they do it is very small in relation. Actually, it could be argued that Jupiter is in fact a failed star. I can't remember the exact name for it, but when a gaseous entity has so much mass and a certain radius, it will collapse on itself and begin the process of nuclear fusion. I think Jupiter is just this side of that requirement.

Well that's just retarded. Next thing you know, they'll catagorize all the objects in inner and outter asteroid belts as planets. Some of the large planets in the solar system have satellites bigger than pluto, a planet which should've been catagorized as an outter asteroid belt object. These scientists are puffing the good shed overtime in their little labs.

 

[flexy]

those scientists must be smoking the crack pipe.

Everyone knows the 12th planet is Planet X (or Nibiru)...inhabitated by the Annunaki.

dvmba$$es scientists

And, in other news, old people who like to play trivia are now baffled when they get the 'How many planets are in our solar system?' question incorrect.

I wonder if I will remember that we actually have 12 planets the next time it comes up for whatever reason.
