The
Name of Pluto
Articule write in "ASTROLOGIA" Nº107, 1986 Buenos Aires.
Patrick Moore writed a articulate in the "SKY and TELESCOPE" in November
of 1984, with a commentary of the Astrologer AL Morrison, that said: The
14 of March of 1930, the English newspapers published the news of
develoment of a new planet. Family MADAN of strong Oxfords tapeworm
connections with the Astronomy.
F. Madan Down Stair,like it was his custom, to have breakfast in the
morning to the 8 Hours ". Their daughter and her granddaughter
VENETIA, were the onlyone that were in the table. Talking about to
the new planet, Madan I ask, "That it names we will put to him".
In this commentary until now inedit, with a minute or two, Venetia said,
" to be called PLUTON".
Venetia Burney ( 11 años )
The devises to seem immediately good. She learned about old mitology
Greek and Latin and also the relative distances to planets in the school.
Madan I leave to a note in the house of H.H. Turner (Professor of
Astronomia in Oxford) and but late during the day it let another note
suggesting send a telegram to the
United States. Of return the satarday one from London, one reunion in
the Real Society of Astronomia, Turner answered inmediatly. Reunion of
the Real Society of Astronomia I do not get to think on the name with
exception of "Kronos" but Turner said "but this Saturn already". Turner
to took the note of Madan to the 3 hours 30 minutes of the Satarday and
sended a telegram after to the United States.
The name of Pluton was recommended finally by the Lowell Observatory in
Flagstaff, Arizona, in Circulate of the 1 of May of 1930, this date
marks asi the "official Adoption" of the name, the proposed Gift was PL.
Was like the small Vanetia Burney of 11 years, I name the "Gentleman of
the Subworld", as it is in the vestibule of his dark kingdom.
PLUTON was discovered the 18 of February of 1930 to Hours 23:07:50 TU
(my time rectified) in the Observatory of Lowell in Flagstaff; by
Clyde Tombaugh.
ASC=0º50'Leo;MC=19º42'Aries The Announcement I make
Tombaugh the Birthday of Lowell the one
that also with the anniversary
of the Uranus discovery (13 March 1781) Lowell born the 13 of March 1855
in Boston, to 12:29 TU.

Astronomers
say "Pluto is NOT a planet"
FUENTE: CNN
What this means is that
Pluto has been ejected from the planetary brotherhood. It is
no longer considered a planet, but a dwarf planet. As a result,
the solar system shrunk today by 1 planet, meaning that the
solar system now consists of 8 recognized “planets” Mercury,
Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.
In short, a “planet” is now 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 neighborhood around its orbit.
This marks the first time the IAU has put forth scientific
criteria for a planet and voted on it. A new distinct class of
objects called “dwarf planets” was also defined as the
astronomers agreed that “planets” and “dwarf planets” are two
distinct classes of objects.
A dwarf planet, according to the new
definition, 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 neighborhood around its
orbit, and (d) is not a satellite.
All other objects orbiting
the Sun will now referred to collectively as “Small Solar System
Bodies."
The first members of the “dwarf planet” category are Ceres,
Pluto, and 2003 UB313 (aka Xena). More “dwarf planets” are
expected to be announced by the IAU in the coming months and
years. Currently, about 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
Resolution 5A is the principal definition for the IAU usage of "planet"
and related terms. Resolution 5B adds the word "classical" to the collective
name of the eight planets Mercury through Neptune.
Resolution 6A creates for IAU usage a new class of objects, for which Pluto
is the prototype. Resolution 6B introduces the name "plutonian objects" for
this class. The Merriam-Webster dictionary defines "plutonian" as:
Main Entry: plu • to • ni • an
Pronunciation: plü-'tO-nE-&n
Function: adjective
Usage: often capitalized
: of, relating to, or characteristic of Pluto or the lower world
After having received inputs from many sides -- especially the geological
community -- the term "Pluton" is no longer being considered.
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 planet1 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 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.
RESOLUTION 5B
Insert the word "classical" before the word "planet" in Resolution 5A,
Section (1), and footnote 1. Thus reading:
