In August of 2006 the International Astronomical Union (IAU) redefined the term "planet", and classified Pluto, Ceres, and Eris as dwarf planets. Pluto is also classified as the prototype of a family of trans-Neptunian objects. After the reclassification, Pluto was added to the list of minor planets and given the number 134340.

nothing happened to pluto. 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.

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 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.

All planets except Pluto orbit the sunlight interior an identical elliptical plane, with common elliptical orbits. the interior 4 planets are small, rocky planets and the subsequent 4 are gaseous giants. Pluto's orbit varies as a lot as 17 tiers above to 17 tiers lower than the plane of the ecliptic. also, it really is orbit is so abnormal that at circumstances it isn't the outermost planet, yet lies contained in the orbit of Neptune. This surpassed off for various years in the course of the Nineteen Eighties and Nineteen Nineties. also, it really is neither a rocky planet nor a gasoline large, yet a small, on the whole ice-ball. And it really is diameter is smaller than that of earth's moon. those days numerous image voltaic orbiting bodies were talked about and more than a number of alternative named, inclusive of Sedna. previous Pluto there are 2 large clouds of small asteroid, the Oort Cloud and the Kuiper Belt. they are the source of comets, that are asteroids that fall in the route of the sunlight, their tail being produced through ice evaporating and being blown again from the picture voltaic wind. So Pluto is extra like the asteroids of the Oort Cloud yet which received a superior orbit. because of those features, Pluto changed into demoted to a Planetoid, or a Planetesimal or an asteroid (any call is universal). What constitutes a planet is basically what scientists call a planet. each and each of the asteroids contained in the asteroid belt orbit the sunlight, yet none is a planet (the biggest, Ceres, is only 3 miles throughout the time of).

Nothing at all happened to Pluto itself -- we folks here on earth just defined the word "planet" more precisely, and with that revised definition Pluto doesn't qualify as a planet. It's a planetoid. We just changed what we call it, nothing happened to Pluto itself.

It's important in science that terms be precise, and are used consistently. It would be confusing to label something with a particular word, when it's significantly different from all of the other things we label with that word. This was long overdue, despite the emotions involved.

Nothing has happened to planet Pluto. It is minding its own business ,unmindful of me or you.It is still existing, it is not dead,while life goes on , Pluto is still orbiting. There are many ' Plutos' around. e.g , the bus system where I live is awful; some-times I wonder if my area has been written off the bus schedule , like how scientists want to pretend that Pluto is no-more.

What everyone said is the same answer I have, also ever since Pluto was found they have been in debate about whether or not it should be classified as a "planet", so finally they decided to demote it's status.

Pluto has been demoted. He is no longer considered a major Disney character and has been re-classified as a canine sidekick.

The IAU decided it wasn't a planet,but rather,a "dwarf planet"

It was seperated into a different new class of planets called "dwarf planets"
