pluto is not a planet. pluto and charon are considered a binary system, but two small bodies orbit this system. they are called nix and hydra. this does not change anything about the solar system or pluto. it just corrects the mistake of classifying pluto as a planet initially.

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 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.

That is interesting. Just say that something is no longer something and it blows up. All I have to do is say that Jupiter is not a planet (it's a black dwarf star instead) and it will blow up.
No, astronomers officially declared Pluto was not a planet. Many astronomers have regarded Pluto as a non-planet since the early 1980s, after its satellite Charon was discovered. This has absolutely nothing to do with Pluto itself. It continues orbiting the Sun and rotating like it always had. What has changed is the sounds and scribbles that an ape species (homo sapiens) now makes when it refers to this world.

What planet Pluto? There's a small rock out there that some people call Pluto... is that what you're talking about? No, it's still there (and it still thinks we suck) Wayne

Pluto, the last planet to join the heavenly pantheon, became the first to leave it. The status of Pluto had been under discussion for some time, but with the discovery of 2003 UB313, nicknamed Xena, the question became acute, for it seemingly had as much right as Pluto to be called a planet.
On August 24, 2006, the International Astronomical Union surprised the world by voting in a new definition of planet, one that would exclude Pluto and bring the total number down to eight. (There had previously been been strong speculation that the redefinition would bring the total up to 12 instead of down.)
Pluto was instead classified as a dwarf planet, along with Ceres and the aforementioned Xena. The main difference between a dwarf planet and the real thing is that the dwarf variety has not cleared the area of its orbital path.
This redefinition met with a wave of protests from those who wanted to see the ninth planet grandfathered in, including but not limited to supporters of the late Clyde Tombaugh, who discovered Pluto in 1930. His widow, however, said he would have been accepting of the IAU's decision since "he was a scientist" and understood that astronomers had to take into account newly discovered objects in the Kuiper Belt (where Pluto is located).
But opponents of Pluto's demotion remain unconsoled and have generated a thriving industry in T-shirts, mugs and other memorabilia. Among the many slogans of this movement was one which played on the mnemonic for the names of the erstwhile nine:
"My! Very educated morons just screwed up numerous planetariums."

Nothing happened to Pluto.
They just decided it's not a planet.

No, astronomers just decided that they were wrong to have called it a planet when it was discovered. It was originally called a planet because they thought it was bigger than we now know it to be. Now it is considered a dwarf planet. But it is still there.

no, Pluto is just a rock caught in orbit around the sun
