Freinds Here i am like to present my interpretation of the Draft Resolution 5 for easy understanding.

Words in Red Colour and Magenta are my additions trying to trace the origin of various reports which we are reading in various websites and newspapers.

My sole intention is to carry forward my previous article, with an effort to make people understand the thing which would revolutionise our world.

My Interpretation of Draft Resolution 5 for GA-XXVI: Definition of a Planet

Introduction :

Contemporary observations are changing our understanding of the Solar System, and it is important that our nomenclature for objects reflect our current understanding. This applies, in particular, to the designation “planets”.

Origin of Word Planet is explained here:
The word “planet” originally described “wanderers” that were known only as moving lights in the sky.

Reason of Definition and Upper Limit can be understood from this part of definition:
Recent discoveries force us to create a new definition, which we can make using currently available scientific information. (Here we are not concerned with the upper boundary between “planet” and “star”.)

Here we can see the exact words used to define the word planet under this resolution

Definition:
The IAU therefore resolves that planets and other Solar System bodies be defined in the following way:

(1) A planet is a celestial body that
(a) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, and
(b) is in orbit around a star, and is neither a star nor a satellite of a planet.


Explanation : Shape : This generally applies to objects with mass above 5 x 1020 kg and diameter greater than 800 km. An IAU process will be established to evaluate planet candidates near this boundary.

Satellite of a Planet : For two or more objects comprising a multiple object system, the primary object is designated a planet if it independently satisfies the conditions in this draft. A secondary object satisfying these conditions is also designated a planet if the system barycentre resides outside the primary. Secondary objects not satisfying these criteria are “satellites”.

Under this definition, Pluto’s companion Charon is a planet, making Pluto-Charon a double planet.


Classical Planets and other sun orbiting planetary objects have been distinguished here – Recognition to ceres as planet had been made – Here

(2) We distinguish between the eight classical planets discovered before 1900, which move in nearly circular orbits close to the ecliptic plane, and other planetary objects in orbit around the Sun.
All of these other objects are smaller than Mercury. We recognize that Ceres is a planet by the above scientific definition.
For historical reasons, one may choose to distinguish Ceres from the classical planets by referring to it as a “dwarf planet.”


Explanation : Dwarf Planet : If Pallas, Vesta, and/or Hygeia are found to be in hydrostatic equilibrium, they are also planets, and may be referred to as “dwarf planets”.


Recognition of Pluto – Orbital Period – Highly Inclined Orbits – Eccentricities along with new word "pluton" is talked herein

(3) We recognize Pluto to be a planet by the above scientific definition, as are one or more recently discovered large Trans-Neptunian Objects.

In contrast to the classical planets, these objects typically have highly inclined orbits with large eccentricities and orbital periods in excess of 200 years.

We designate this category of planetary objects, of which Pluto is the prototype, as a new class that we call “plutons”.

Reference to Minor Planets had been made here which now replaced by the word “Small Solar System Bodies” :

(4) All non-planet objects orbiting the Sun shall be referred to collectively as “Small Solar System Bodies”.

Explanation : Small Solar System Bodies: This class currently includes most of the Solar System asteroids, near-Earth objects (NEOs), Mars-, Jupiter- and Neptune-Trojan asteroids, most Centaurs, most Trans-Neptunian Objects (TNOs), and comets. In the new nomenclature the concept “minor planet” is not used.

Source:IAU, Kindly refer to IAU proceedings at Prague for more information and original copy of this draft resolution.

I do hereby urge the scientific community all over the world to execute a mass movement of education among student community and general public before some selfish people with vested interest take advantage of ignorance in general public.

thank you

Yes, we certainly needed another topic about the IAU definition of a planet; I agree with you that there were far too few already, and indeed suggest that every member of this forum start their own thread about their definition of a planet. Not.

Edit: Oh, and it's extra ungood to post the same article in different places.
Moderator, if you remove one or more of them, feel free to delete my nag.

Thanks, but if you go to the "Astronomy" forum, you'll see that we've been discussing this since it became public. We've been discussing (and arguing) the planet definition issue for much longer. Feel free to add your own opinions. Personally, I like the draft, though there are some details I'd change.

We have a number of threads already dedicated to the topic. Please feel free to participate in the existing discussions:

Pluto's a planet! (And Ceres and Charon and ... )
Does anybody feel that we are taking public opinion too seriously?
International Academy of Astronomy deciding to include...
Is Pluto a KBO or planet?
let's give credit to the IAU
Do you approve IAU planet definition?
If one more person asks me about the definition of "planet" ...
Calling Titan a planet: setting a precedent?
why don't they do this...
New planet mnemonic device
Antares is that big?
