So, Pluto is no longer a planet. Yay for 8 planets now!
This completely messes up my reality. Up is down, black is white! What's next???

I don't understand how a planet can be demoted? What on earth are those scientists doing? Having meetings about whether or not demoting the next planet Venus maybe?

i think it measn Pluto is no longer considered to be in our solar system. Or something.

It's in our solar system I believe, it just isn't considered a planet... I think I heard them call it something like a "dwarf planet" on the news. So what the hell does that make the moon?

So Pluto has been a planet all this time and all of a sudden it's not anymore? I guess the Earth wont be called a planet soon too, rather a big pile of trash...

- Moons (there are many!) are sizeable objects circulating a planet, not the sun.
- our solar system, as such, extends well beyond Pluto.
- The main arguments for the demotion were the lower mass of Pluto in comparison to the remaining planets, and the fact that the other eight circulate in one plane, whereas Pluto's track is tilted indicating it to be a later 'catch' by the solar system versus being formed out of the original dust cloud.

The moon was a moon last time I checked... (Check Glance's description if you don't know what a moon is .) Pluto is melting away (due to it being frozen and exposed to the sun), so I guess it's shrinked too much to be called a planet now. And that's why it used to be a planet but isn't any more. Übereil |

I think the theory is that prior to this announcement there was no "clear" definition of what a planet is. They have now defined a planet as an object that orbits a star and is not a satalite, and has cleared the surrounding space of other debris. A dawaf planet is one that hasn't cleared the surrounding space around it.

Here is a run down of how the conference came to the understanding of why Pluto is not considered a planet. Not terribly gripping news, but maybe it will explain why Pluto is not a planet anymore. Aug 17 Aug 20 Aug 24Aug 24 Aug 25Last but not least the definition. This will help to explain why Pluto is not a planet and why earth is. Aug 25 |

According to my mothers the Yanks are freaking over this  . For one they're sending a satelite there, and for another, THEY were the ones who discovered it. AND they were allso the ones who did this (talk about stabbing yourself in the back  ). Übereil |

The scientists created a new definition of "planet" because the whole question of exactly what constitutes a planet has been bothering them for ages. Are planets anything that orbit a star? Well then all the asteroids in the asteroid belt would have to be a planet. Here's the definition they came up with;
"Pluto, a planet since 1930, got the boot because it didn't meet the new rules, which say a planet not only must orbit the sun and be large enough to assume a nearly round shape, but must "clear the neighborhood around its orbit." That disqualifies Pluto, whose oblong orbit overlaps Neptune's, downsizing the solar system to eight planets from the traditional nine."
The main reson for demoting Pluto is because they showed it's not really a unique object, like the other planets are. It's very small, so small that scientists have discovered several other objects similar in size, but which aren't planets, like the asteroid Ceres. Even Pluto's "Moon", Charon, is nearly half of Pluto's size, a clear indicator that calling Pluto a planet is a problem.
It's gonna be a little weird adjusting to a solar system with only 8 planets, but I'm fairly sure it will be a smooth transition.
