Re: [escepticos] Definición de Planeta

Entiendo que ya hay humo blanco:

<<IAU 2006 General Assembly: Result of the IAU Resolution votes
(...)
The IAU members gathered at the 2006 General Assembly agreed that a
"planet" is defined as 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.
This means that the Solar System consists of eight "planets" Mercury,
Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. A new
distinct class of objects called "dwarf planets" was also decided. It
was agreed that "planets" and "dwarf planets" are two distinct classes
of objects. The first members of the "dwarf planet" category are
Ceres, Pluto and 2003 UB313 (temporary name). More "dwarf planets" are
expected to be announced by the IAU in the coming months and years.
Currently a dozen candidate "dwarf planets" are listed on IAU's "dwarf
planet" watchlist, which keeps changing as new objects are found and
the physics of the existing candidates becomes better known.>>

Me surgen dos dudas:

¿Dónde quedó Caronte?
¿Cuál (o cuáles) de las condiciones para ser planeta no cumple Plutón?
