 Plutón no mantiene limpio su vecindario ;-)

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?
