pluto is not a planet, but pluto orbits the sun, is round, does not have an isolated orbit (a bunch of other similar bodies have similar orbits.), and is not a satellite so it is a dwarf planet. this does not change anything about the solar system or pluto. it just corrects the mistake of classifying pluto as a planet initially.
this same thing has happened before. beginning in 1800, astronomers found a few bodies orbiting between the orbits of mars and jupiter, and they finally stopped calling them planets after the fourth discovery. astronomers then added numerals to the names, and pluto recently got its numeral. 150 years from now, no one will think of "134340 pluto" as a planet. very few will even know we classified it as a planet. "1 ceres" and "136199 eris" are other dwarf planets.
i have been waiting for this since i was about twelve. i feel somewhat satisfied. i knew that pluto didn't fit the pattern set by the major bodies in the solar system so it was an anomaly. it just felt illogical and "out of place". this was the right thing to do, believe me. i don't understand why so many are having such a problem with this.
i don't know how long this will drag on tho. many planetary scientists are not satisfied that the definition is rigorous enough.

Science is governed by definitions, axioms, theorems, logic, etc. It is precise and it is unemotional - which is exactly how is SHOULD be. While we may have grown some sort of "attachment", emotionally, to Pluto being a planet - the word "planet" has to mean something -- a generalization or abstraction of certain types of heavenly bodies. The definition of the word "planet" was recently changed - and Pluto simply no longer fits that definition and is therefore no longer a planet. So - no - I don't think of Pluto as being a planet anymore - because it isn't one. It's not a matter of opinion - it's a matter of fact. However - don't let this change of classification annoy you too much. Pluto is still out there in our solar system -- it's not going anywhere....you can still appreciate Pluto for being what it is - despite no longer being classified as a planet.

well i think so that pluto is a planet but main thing we have to keep in our minds is that the palnet pluto is small as compare to other in our planets family so it got less gravitational fourse though it got more chances of having life on it then of mars but this world runs with rules not with emetions so if we are seeing pluto as a planet only because of our emotions or that it has ben a part of our family frm such a long time and ignoring the facts on which a planet is described i think thats is wrong

YES...I misss pluto! Why do they scientist think that they are just so high and mighty that they can just take a planet away from us. Pluto has been a planet for years and years so why change it? There is no reason to change it...so why did they do it because the only affect it has is that schools are going to have to pay tons of money for new science books. I think kicking pluto out was wrong.!

I was brought up believing that it was a planet. However, what's in a name?
If the definition of a planet is changed, and it doesn't include Pluto, then we just have to think differently. Wanting to believe it doesn't make it so.

No. A dwarf planet can be a good name. However, the reason why is fully arbitrary.
They made a fully arbitrary decision, with no clear borders what so ever. You need a strict mathematical model, that's the only good way. With strict borders. Like: at least 0,001% diameter of the sun. Or: at least 0,00001% mass of the sun. And so forth.
