no, really, pluto is not a planet, but some consider pluto and charon to be a binary system, and 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.

http://en.wikipedia.org/wiki/Pluto
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 several discoveries. 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.

Pluto is now in the new category of a "dwarf planet", so it's almost a planet but now a big one.
This was caused by the discovery of "Eris" which is now also a dwarf planet. People sisn't want that to become a planet, but it's bigger than Pluto so they made this new category

Pluto is now classifed a dwarf planet because it failed to meet one of the new rules that were put down by the IAU. The rule was, "The object must dominate and clear the neighbourhood around it's orbit". Since there was heaps of little asteroids and things that are over 100 km around the orbit of Pluto It was demoted.

It is not still considered a planet. It was demoted to planetoid.

Maybe we should wait to tell whether it is or is not a planit untill we land somthing on it and interview the things that live there.
It could be that they have voted and say that Eirth is not a planit
