The liars and con artists of the International Astronomical Union have demoted Pluto from "planet" to "not a real planet". What a load of bunk! It's politics, not science.
Saying a "dwarf planet" (Pluto) is "not a planet" is like saying a small person (dwarf or child) is not human. Google "Pluto is planet" and see the links to all the raging controversies. Even Wikipedia has locked up the Pluto page "due to vandalism". Man, this is Interplanetary Blogocombat at its best!
Children watched the news report: Pluto is too little to be planet. Sad faces. They're little, too. Thus, insignificant?
Pluto not a planet?
Now, the politically correct planet must be: orbiting sun, round, tidy. (See IAU quote below). This is a scientific definition? Why round? A planet cannot be boxy, lumpy, or square? There is a square shaped galaxy, you know.
Disgruntled pseudo-astronomers, angry that NASA is sending a probe to Pluto for the first time, are using the sour grapes approach: "Big deal, you're going to Pluto. As far as we're concerned, it's not even a planet. In fact, we'll re-define it as a non-planet."
Textbook publishers are very pleased. Now schools have to upgrade their astronomy curriculum to reflect the change.
Pluto to Earth:
"LOL. I don't clean up my neighborhood? How about your neighborhood, Earth? How clean is it?
You're full of orbiting space junk debris, pollution, crime, war, rape, gambling, gluttony, addiction, insanity, genocide, and global warming...yet you lecture me about a clean neighborhood? You suck. Maybe we planets should vote on a resolution to demote Earth from planet to freakazoid. Bite me."
IAU Resolution: Definition of a Planet in the Solar System
Contemporary observations are changing our understanding of planetary systems, and it is important that our nomenclature for objects reflect our current understanding.
This applies, in particular, to the designation 'planets'. The word 'planet' originally described 'wanderers' that were known only as moving lights in the sky. Recent discoveries lead us to create a new definition, which we can make using currently available scientific information.
The IAU therefore resolves that "planets" and other bodies in our Solar System be defined into three distinct categories in the following way:
(1) A "planet"1 is 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.
(2) A "dwarf planet" is 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) shape2 , (c) has not cleared the neighbourhood around its orbit, and (d) is not a satellite.
(3) All other objects except satellites orbiting the Sun shall be referred to collectively as "Small Solar-System Bodies".
1 The eight planets are: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.
2 An IAU process will be established to assign borderline objects into either dwarf planet and other categories.
3 These currently include most of the Solar System asteroids, most Trans-Neptunian Objects (TNOs), comets, and other small bodies.
