Финалната '''дефиниција на''' поимот '''планета''' е донесена на [[24 август]] [[2006]] <ref>{{cite news|url=http://www.iau2006.org/mirror/www.iau.org/iau0603/index.html|title=IAU 2006 General Assembly: Result of the IAU Resolution votes|publisher=IAU|date=24 August 2006|publisher=IAU}}</ref>, is
{{cquote|The IAU...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) shape [2], (c) has not cleared the neighbourhood around its orbit, and (d) is not a [[satellite]].
 
(3) All other objects [3] except satellites orbiting the Sun shall be referred to collectively as "[[Small Solar System Bodies]]".
 
Footnotes:
 
[1] The [[Planets#Within_the_solar_system|eight planets]] are: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.<br>
[2] An IAU process will be established to assign borderline objects into either "dwarf planet" and other categories.<br>
[3] These currently include most of the Solar System asteroids, most Trans-Neptunian Objects (TNOs), comets, and other small bodies.
 
----
 
The IAU further resolves:
 
Pluto is a "dwarf planet" by the above definition and is recognized as the [[pluto_prototype|prototype]] of a new category of [[trans-Neptunian objects]].}}
