Rants from a rootbeer drunkard

A lot has happen lately...
for starters.. the Pluto incident..
Disney's fav dog shall lose fame BIG time...
when Pluto gets stripped off its position in the solar system...

after 76years of 9 planets revolving.. we drop a bombshell and there goes the ninth...
if u noe the siginificance..
all knowledge should be drop abt those planets revolving..
they probably gonna name pluto on another system..
http://www.iau.org/

Maybe pluto shall be on some belt.. like orion etc.. (MIB crap)

Well here's a quote on what a planet is:
The part of "IAU Resolution 5 for GA-XXVI" that describes the planet definition, states "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."

It sound damn much like those regulations and thingy i've been reading..
Maybe i haven said enuff.. but those on top of these is the OLD rulings and definition of planets..

Here's the new scoop:

According to the new draft definition, two conditions must be satisfied for an object to be called a "planet."

First, the object must be in orbit around a star, while not being itself a star.
Second, the object must be large enough (or more technically correct, massive enough) for its own gravity to pull it into a nearly spherical shape. The shape of objects with mass above 5 x 1020 kg and diameter greater than 800 km would normally be determined by self-gravity, but all borderline cases would have to be established by observation.

Ok, reverse of thoughts.. the above would have caused the solar system to have 12 planets...

Which was not what truly happened...

Here's the cold hard truth:

-------------------------------------------------------------
RESOLUTIONS

Resolution 5A is the principal definition for the IAU usage of "planet" and related terms.
Resolution 6A creates for IAU usage a new class of objects, for which Pluto is the prototype.

The IAU will set up a process to name these objects.

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.

RESOLUTION 5A
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 objects3 except satellites orbiting the Sun shall be referred to collectively as "Small Solar-System Bodies".
1The eight planets are: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.
2An IAU process will be established to assign borderline objects into either dwarf planet and other categories.
3These currently include most of the Solar System asteroids, most Trans-Neptunian Objects (TNOs), comets, and other small bodies.

IAU Resolution: Pluto

RESOLUTION 6A
The IAU further resolves:Pluto is a "dwarf planet" by the above definition and is recognized as the prototype of a new category of trans-Neptunian objects.1
-------------------------------------------------------------

So now pluto is going down the history books with 3 other drawf planets, including xena(quoted in many astronomy books as Planet X)...
sad but its gonna end like this..
At least they din throw it into another system..

Tmw's a math mock.. so sian..
so tired..
burry myself in books...
