Final Draft Proposal
The final, third draft definition proposed on 24 August was:
| “ | The IAU...resolves that planets and other bodies in the Solar System be defined into three distinct categories in the following way:
(1) A 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, 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, (c) has not cleared the neighbourhood around its orbit, and (d) is not a satellite. (3) All other objects orbiting the Sun shall be referred to collectively as "Small Solar System Bodies". The eight planets are: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. An IAU process will be established to assign borderline objects into either dwarf planet and other categories. These currently include most of the Solar System asteroids, most Trans-Neptunian Objects (TNOs), comets, and other small bodies. |

Famous quotes containing the words final and/or draft:
“The self-explorer, whether he wants to or not, becomes the explorer of everything else. He learns to see himself, but suddenly, provided he was honest, all the rest appears, and it is as rich as he was, and, as a final crowning, richer.”
—Elias Canetti (b. 1905)
“News is the first rough draft of history.”
—Philip L. Graham (1915–1963)
