628.1 | Conventional Astronomical Data | CIMNET::PIERSON | | Fri Jan 15 1988 12:42 | 8 |
| The Globe had a piece on this also. The moon of Pluto is
believed to be large, 20-30% as massive as Pluto(?). This data
is based on analysis of a series of eclipses of Pluto by its
moon which have occurred over the last few years. Additional
analysis is taking place

Astrology is already having to think about this issue of
sign rulership. The discovery of the minor planet Chiron
in 1977 has already started this thinking process. There
is one school of thought that has Chiron ruling Virgo,
which currently shares Mercury with Gemini. Taurus and
Libra share Venus. Also being considered are the major
asteroids Ceres, Juno, Pallas Athene, and Vesta and how
they fit into the newly forming picture, as well as the
possibility of undiscovered planets existing.
As humanity evolves and becomes aware of new dynamics of
the human psyche and its spiritual source, so to do the symbols
encompassing these archetypes of the psyche become available
for our study and use.

| It isn't so much as a brand new discovery, as someone proposing
that we've had enough evidence now for a while to indicate that
there may be a better way of describing the Pluto/Charon system
than as a planet and satelite.
Two observations are relevant:
It appears that Charon is large enough relative to Pluto so that
their common center of gravity about which they rotate is above
the surface of Pluto. Although its a brand new definition, it seems
reasonable to place the distinction between a planet-moon combination
and a double planet combination at that division point.
The second is that the "atmosphere" of Pluto has recently been
observed and it is detectable out *further* than Charon. In a sense
their atmospheres are shared. This really says less than it sounds
like though. Atmospheres don't stop abruptly, but rather tail off.
In principle if we had sensitive enough instruments we could
demonstrate that all the solar planets "share" an atmosphere.
Certainly the area around the Earth/Moon system shows a higher
density of gas than surrounding space, so, in a sense the Earth
and the Moon also share an atmosphere. The sharing between Pluto
and Charon is pretty high relative to their atmospheres, but both
atmospheres are rather tenuous by planetary standards.
The first was suspected virtually from the time Charon was discovered,
though nobody thought of it in double-planet terms, and it has become
more certain as more data has been collected. The second is relatively
recent, I would say I first saw it mentioned (nice cover picture
demonstrating a picture of the "shared" atmosphere in Science News)
about 5 or 6 months ago.

| So is Chiron the mysterious 10th planet?

628.5 | RE 628.4 | DICKNS::KLAES | All the galaxy's a stage... | Sun Jan 17 1988 12:15 | 22 |
| No, Chiron just happens to be a relatively large (400 miles
in diameter) planetoid (asteroid) which orbits Sol between the
true planets Saturn and Uranus. The largest planetoid known,
Ceres - which orbits Sol between the planets Mars and Jupiter,
where most planetoids dwell in our Solar System - is roughly 600
miles in diameter, and even it is not considered to be a full-fledged
planet.
An alleged tenth planet, which supposedly lies beyond Pluto,
has yet to be discovered.
Incidentally, in recent years, new studies on Pluto have made
some astronomers claim that Pluto is not a "true" planet, but rather
a very large planetoid (or even a comet!). Roughly 1,800 miles
in diameter, it is smaller than the true planet Mercury (3,100 miles)
and even many moons, including Earth's moon, Luna (2,160 miles)!
If this idea is accepted by the astronomical community, it would
effectively make Pluto's moon, Charon (600 miles), a planetoid as
well, thereby making Pluto and Charon the first known double planetoids.

What's the difference between a planet and a planetoid???

| Re .6 (Carla):
What's the difference between a minicomputer and a microcomputer?
In Digital's case, it seems to be "a microcomputer has a Q-bus;
a minicomputer doesn't." Likewise, the difference between a planet
and a planetoid is definitional.
Luna (Earth's moon) is 2,100 miles in diameter; that's a hefty size;
but it's a moon. Titan, one of Saturn's moons, is bigger than
Mercury, but it's a moon. Pluto is smalkl, but it's the biggest
chunk of matter in its orbit. So why isn't it a planet? I say
it is; because it's been defined as a planet.

628.8 | It's the size and location that counts | DICKNS::KLAES | All the galaxy's a stage... | Mon Jan 18 1988 08:17 | 17 |
| To be a bit more distinct, a planet is usually defined as a
nonluminous celestial body which orbits a star. Now I realize that
planetoids and moons orbit Sol as well, but moons are defined as
such when they orbit a world which is larger than themselves -
Jupiter's Galilean moons are large enough to be planets in their
own right, but because they orbit Jupiter (which is much larger
than them), they are designated as moons.
For planetoids it is mostly a matter of size, plus the fact
that there are so many of them (roughly 5,000 at the latest count),
which keeps them from having full-planet status. At the present
time, any celestial object smaller than Pluto (1,800 miles) is
considered to be a planetoid, and Pluto itself may one day be
designated as a planetoid.

628.9 | Chiron vs Charon. | PBSVAX::COOPER | Topher Cooper | Mon Jan 18 1988 14:22 | 36 |
| Some confusion may have crept in for some readers since we have
been talking about two different objects with very similar names.
One is *Charon* the relatively recently discovered companion to
Pluto (more discussion of that in a moment). Charon is named, quite
appropriately after the mythical fairyman who transported the souls
of the dead into Hades, Pluto's domain.
The other is *Chiron* a rather large asteroid. Chiron is named
after the centaur who trained Hercules, Jason and Achilles, among
others in Clasical mythology. It is a completely different chunk
of rock.
The "10th planet" refers to a new, as yet undiscovered, planet
beyond the orbit of Pluto. Certain anomalies in the orbits of
comets and of the other planets might indicate that there is such
a planet (or it might indicate some subtle flaw in the chain of
assumptions being used -- the error is very, very small).
The proposal that Pluto/Charon be considered a double planet is
a little more terminologically far-reaching than is at first obvious.
A spot of light was discovered in the 30's and was dubbed Pluto.
We now know that that spot of light came from two distinct bodies
in orbit around each other. Most of the light came from the larger
body, but a signigicant portion comes from the smaller. Following
the traditional planet/moon dichotomy it was natural to take the
larger body as the planet already dubbed Pluto, and the smaller
body as its moon newly dubbed Charon.
The double planet proposal, in effect, says that Pluto/Charon
*together* should be considered "the" planet with two components Pluto
and Charon. These will probably end up also being called "planets"
but it seems to me that it would actually make sense to call them
both moons -- of each other.

Re -.9, a bit of nit-picking:
Charon poled the ferry that took dead souls across the River Styx,
and is therefore a ferryman...the practice of putting a coin with
the body of the deceased (often under the tongue) was to provide
the fare for the trip across the waters.

628.12 | A few speculations on meaning | NATASH::BUTCHART | | Mon Jan 25 1988 16:38 | 75 |
| The base note had the question What does this mean for Scorpios?
I've had these musings.
Two years ago I finally bought Jeff Green's compelling book titled
_Pluto: The Evolutionary Journey of the Soul_. One of his major
theses is that our desire nature is dualistic. We have a desire
to be separate, and a desire for union (he refers specifically to a
union with God or Creator--whatever term you prefer). He believes
that the interaction of these dual desires, and our actions that
spring from them, are the main fuel for our karma. And he believes
that Pluto is the planet that represents this duality and the karmic
struggle in our birth charts.
I stretched a bit at first in the beginning to imagine the idea.
But as I began to read more and more astronomical speculations that
the "planet" Pluto is actually a dual system of moons/planets/
planetoids/comets/whatever, the dualistic desire nature idea began
make more metaphysical sense. Even though astrology is only a model,
that model has its springboard based in physical reality. Following
this line of reasoning, many astrologers of my acquaintance believe
that the physical properties of the planets give hints as to their
metaphysical meanings. If "Pluto" is, in fact, two hunks of rock
orbiting each other, perhaps Jeff's thesis about it being
representative of a dualistic desire nature is quite correct.
Musing on all this, doesn't it feel like the sign Scorpio has
a very deep esoteric meaning? Most of the bad press I've heard
about Scorpios runs along the lines of "obsessed, secretive, dark,
too intense, controlling, overly concerned with sex, death, and
money, greedy, jealous." Even those who praise Scorpios are somewhat
guarded; much of what I've read is along the lines of "Well, you
Scorpios are certainly dealing with Important Issues, but you're
just Not All That Nice, and you should really Clean Up Your Act
or you'll end up being a Really Rotten Person and Destroying Everything."
If the Scorpios out there have heard too much of this and believe
it is worth noting that none of the great villians of the 20th Century
(Hitler, etc.) were/are Scorpios (although I admit I don't know
about the Ayatollah).
So it seems to me that if Jeff Green is correct, Scorpios have chosen
a mission in this incarnation (for those of you who believe that
way) to deal directly with resolving issues that concern this
separation/union conflict. Not all the difficulty you may experience
is your fault; societal training is pretty pitiful when it comes to
teaching anyone, not just Scorpios, how to deal with the desire
nature, and the dual drive for separation/union.
One astrologer of my acquaintance also believes that Scorpio and
Pluto are about energy exchange and transformation on a cosmic level.
All the things that Scorpio is about make sense viewed that way.
Sex is the energy of physical desire exchanged; the transformative
result may be just emotional and physical union or it may be new
life. Money is given its considerable power only when it is exchanged
for something. Death is the energy of animation leaving the body
for somewhere else; the body is transformed back to its earthly
elements, and the soul? who knows?
Two bodies, rotating around a common center, symbolise to me a lovely
dance of true equality that is necessary for true exchange to take
place. For Scorpios, it may be quite important that in all efforts
of life, especially with other people, that you "box your own weight".
It is important to make the effort to ensure that both parties bring
everything to the table, uncover the hidden agendas, and deal with
each other as if both of you mattered equally, arrange exchanges
fluidly, instead of trying to make them rigid. It is when this
delicate balance gets out of whack that the "power games" and "control
issues" surface. Scorpio people may be on a mission this time
out to deal directly with these types of issues. Again, societal
training is pitifully inadequate in helping anyone learn to do this
well.
Yours truly,
Ole Pluto Eyes

Remember that scorpios (nor any other sign) aren't the bad
guys. Each of the 12 signs represents a distinct, necessary phase
in the complete cycle of existence. Each individual under a par-
ticular sign has evolving, evolved, and unevolved qualities uniquely
characteristic of that sign. In other words "bad" scorpios exhibit
one group of qualities while, say, "bad" leos have their very own
unique group of qualities. In each case, "bad" just translates to
unevolved.

628.15 | Scorpio Parties | SEINE::RAINVILLE | Edge close to the best view! | Tue Feb 09 1988 07:51 | 12 |
| It seems that most people I spend time with, at work and out, are
Scorpios. I haven't consciously chosen these associates always,
frequently the've been assigned. I first noticed this when my
wife threw a surprise keg party for my 25th. It turned out that
most of my close friends were born in early November. Every Nov.
after that someone had a generic Scorpio party, some of them
lasted 3 days. Last Nov. I disocvered that the 2 technicians I've
worked with (as lead engineer) are also Scorpios. Whenever I work
at a task with others of this Ilk, there seems to be very rapid
understanding of technical points, which are later hard to explain
to others............................................MWR
