The IAU members gathered at the 2006 General Assembly agreed that a "planet" is defined as a celestial body that (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, and (c) has cleared the neighbourhood around its orbit. This means that the Solar System consists of eight "planets" Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. A new distinct class of objects called "dwarf planets" was also decided. It was agreed that "planets" and "dwarf planets" are two distinct classes of objects. The first members of the "dwarf planet" category are Ceres, Pluto and 2003 UB313 (temporary name). More "dwarf planets" are expected to be announced by the IAU in the coming months and years. Aloha

After the discovery of Pluto, it was quickly determined that Pluto was too small to account for the discrepancies in the orbits of the other planets. The search for Planet X continued but nothing was found. Nor is it likely that it ever will be: the discrepancies vanish if the mass of Neptune determined from the Voyager 2 encounter with Neptune is used. There is no Planet X. But that doesn't mean there aren't other objects out there, only that there isn't a relatively large and close one like Planet X was assumed to be. In fact, we now know that there are a very large number of small objects in the Kuiper Belt beyond the orbit of Neptune, some roughly the same size as Pluto.

Almost nobody has seen Pluto through a telescope and yet they clamor for it to remain misclassified. What does anybody care? It's puny, hardly bigger than its moon Charon, has an elliptical orbit and is not in the same plane as the other planets.
It's an oddball, classified as a planet because the media was so excited about it!
Really this is about *change*. People don't like change, even if the change is correct.
The newest dwarf planet is Eris with its small moon Dysnomia. Let's try to be rational and keep up with technology. VCRs are not that hard to program!

What in the world? The qualifications for a planet have changed, and Pluto does not conform with these qualifications, so it is no longer considered a planet.
Science changes all of the time. That's what I love about the biological studies... you never know what might happen and what might change. :)

I know like calling it a micro planet makes it less or whatever...my kids still have to learn about it.........does it really affect our universe as we know it if we change the name too lol! Next thing you know they'll tell us that eggs are micro eggs cuz the dinoaurs where larger!

It is because it does not share characteristics with other planets and because it is so small. They are considering it a dwarf planet now.

Because it probably did not form in the same way that other planets formed.

Because 260 members of the IAU said so.
Let's impeach them!

Its because its so far away that I guess they don't consider it a planet anymore.
