Hey,
Sharpen your pencils all you pippy poindexters here at BABB,
its Colonel Vianova,your favorite GLPer,
Drs Marsden, Brown, Murray , Matese,
and Velikovsky as a casual observer,
are here for a comment or two.
Since Phil would not talk about it.....
Dr P. states that Sedna has a stable orbit, and that there is nothing unusual about it.
Thus I would assume that the huge object ,as suggested in the links by ***Drs Murray and Brown,
be it a brown dwarf or,
huge "body of planetary mass " {as dr P would say},
also has a stable orbit as well.
Comments please on Drs Murray , Matese, Marsden and Browns statements on the highly controversial comments that
IMPLICATE that our solar system is either ,
part of a binary star system ,
with a brown dwarf,
or there may be huge planet{s}
still out there to be discovered that are affecting the comets and outer planets as well.
Royal Astronomical Society, Dr. John Murray,

on comets
they spend millions of years in the Oort cloud, until they are deflected into an orbit that takes them into the inner Solar System where we can see them.
By analysing the orbits of 13 of these comets, Dr Murray has detected the tell-tale signs of
***a single massive object that deflected all of them into their current orbits.
"Although I have only analysed 13 comets in detail," he told BBC News Online, "the effect is pretty conclusive. I have calculated that there is only about a
***one in 1,700 chance that it is due to chance."
In a research paper to be published next week in the Monthly Notices of the Royal Astronomical Society, he suggests that the
***so-far unseen planet is several times bigger than the largest known planet in our Solar System, Jupiter.
Being so far from the Sun - three thousand billion miles - it would take almost six million years to orbit it.
"This would explain why it has not been found," explained Dr Murray to BBC News Online. "It would be faint and moving very slowly."
Opposite direction
He has calculated that it lies in the constellation of Delphinus (the Dolphin).
But the planet orbits our Sun in the "wrong" direction, counter to the direction taken by all the other known planets.
It is this which has led to the remarkable suggestion that it did not form in this region of space along with the Sun´s other planets, and could be a planet that "escaped" from another star.

In the October 11 issue of the Monthly Notices of the Royal Astronomical Society,
Dr. John Murray, an astronomer from the Open University in the United Kingdom proposed that a large object in the extreme outer realms of the solar system may be gravitationally affecting the orbits of long-period comets. He theorizes that the object would have to orbit the sun 32,000 times farther away than Earth (about 3 trillion miles) and would have to be at least as massive as Jupiter, if not more so. Given its distance, it would also be extremely faint and slow moving.
In other research, a professor of physics at the University of Louisiana at Lafayette, Dr. John J. Matese, is making a case for the existence of a 2- to 3-Jupiter mass object orbiting some 2.3 trillion miles from the sun. In a paper soon to be published in the planetary journal, Icarus, Dr. Matese asserts that this object, too,
***has created a "concentration" of Oort cloud comets and is responsible for sending a significant number of them - perhaps as much as 25 percent - into the inner solar system.
Murray´s research suggests that the some of the incoming comets include a group coming from directions in space that are aligned in an arc across the sky. This arc, he asserts, could mark the wake of some large body moving through space in the outer part of the Oort cloud. A similar theme arises in Dr. Matese´s research. His study of 82 Oort cloud comets indicates that approximately 25 percent of these have an "anomalous distribution" in the sky that can best be understood if there exits some perturbing force in the Oort cloud, i.e.,
a large, as yet undetected, body.

Most prominent among these, she says, is the fact that there are more observers in the Northern Hemisphere to discover comets than in the Southern Hemisphere, thus a number of long-period comets are probably escaping detection and analysis
Dr. Matese´s theory focuses on different aspects of long-period comet orbits, but nevertheless begs the question: could the darkest corner of our solar system harbor a tenth planet
***or a brown dwarf?"
Pro brown dwarf
*** "A brown dwarf, he contends, would not have been detected in the previous infrared searches, such as the one conducted by the Infrared Astronomical Satellite (IRAS) in the early 1980s, because the alleged planet/brown dwarf is too near the galactic plane. To ferret out such an object in that busy IR region requires greater sensitivity than IRAS possessed at the time."
Not Brown Dwarf
**"Dr. Murray rules out the notion that the object might be a heretofore undiscovered brown dwarf since, being brighter than a planet, it would probably have been detected by now. He does not, however, rule out other possible explanations for the observed entrainment of comet orbits."
******************************************
Remember Marsdens and browns stuff on Sedna?
Marsden
"How it got there in such an eccentric orbit that comes as close as 76 astronomical units
to our sun and goes all the way out to nearly 1000 astronomical units away is a complete mystery! There might still be something else out there causing this object´s peculiar orbit." * Brian Marsden, Director, Minor Planet Center, Harvard Smithsonian Astrophysical Observatory.
"But even if it sent it into 76 A.U., when then is the aphelion 1,000 A.U. ? There is no way! I can´t think of any way of getting into this orbit, other than having some unknown planet or planets in the range..."
"...still might be something out there affecting Sednas orbit..."...hmmm
"But to be honest, we really don´t know how big this object is. It could even be **bigger than Pluto if it has a very dark surface. Or it could be a lot smaller if it has a very bright surface."
Dr Brown
"...Brown said there is one unexplored region of space left, amounting to about 20 percent of the sky, that hasn't been searched for an Earth-sized object that would be orbiting at 70 AU and presumably in the main plane of the solar system. It is the region toward the bright galactic centre, which is harder to search. Brown said his team is considering making that search now." (7)
"....searching the 20% of the unexplored sky..."..."for an Earth sized object.."...hmmmm
Earth sized object my ***,
Brown is saerching for Murrays,
"so-far unseen planet is several times bigger than the largest known planet in our Solar System, Jupiter."

DEEP IMPACT MISSION
http://neo.jpl.nasa.gov/missions/deepimpact.html
"On July 4, 2005, the Deep Impact mission will impact the surface of comet Tempel 1 thus creating a fresh crater larger than the size of football field and deeper than a seven-story building. The spacecraft will study the crater formation process and examine the subsurface structure of one of the solar system´s most primitive objects, a remnant from the outer solar system formation process. The Deep Impact spacecraft will launch in December 2004 and then encounter comet Tempel 1 on July 4, 2005.
Deep Impact will be the first mission to make a spectacular, football-stadium-sized crater, seven to 15 stories deep, into the speeding comet. Dramatic images from both the flyby spacecraft and the impactor will be sent back to distant Earth as data in near-realtime. These first-ever views deep beneath a comet´s surface, and additional scientific measurements will provide clues to the formation of the solar system."

"The Hubble observations provide clear evidence that very low mass red dwarf stars must have some form of dynamo to amplify their magnetic fields."
His conclusions are based upon Hubble´s detection of a high-temperature outburst, called a flare, on the surface of the extremely small, cool red dwarf star Van Biesbroeck 10 (VB10) also known as Gliese 752B. Stellar flares are caused by intense, twisted magnetic fields that accelerate and contain gasses which are much hotter than a star´s surface.
Though the star´s normal surface temperature is 4,500 degrees Fahrenheit, Hubble´s GHRS detected a sudden burst of
***270,000 degrees Fahrenheit in the star´s outer atmosphere. Linsky attributes this rapid heating to the presence of an intense, but unstable, magnetic field.
***Since VB10 is nearly a brown dwarf, it is likely brown dwarfs also have strong magnetic fields," says Linsky. "Additional Hubble searches for flares are needed to confirm this prediction."
The new Hubble observations suggest a magnetic dynamo perhaps of a new type can operate inside these stars.
These results are being reported at the 185th meeting of the American Astronomical Society in Tucson, Arizona"
This sure goes back to the
Interplanetary Arc thread,
http://www.godlikeproductions.com/bb...owdate=3/19/04
and the recent evidence of brown dwarves with CMEs .
Yea, get one of these red/brown dwarves on an elliptical orbit cruising thru the solar system belting out quarter million degree flares....coming close to planets and moons, and perhaps we get the "electric cratering" mentioned in the arc thread in the astronomers experiment

"Marsden favours an object closer in, a "planetary object," he told Space.com , perhaps at between 400 and 1,000 AU. "Perhaps there's more than one planet out there," Marsden said. "Who knows? But let's suppose it is something of an Earth mass,
****maybe even a few Earth masses.
A close approach could throw this object [Sedna] from something more circular into something more eccentric."

Hey this stuff is a lot better than Planet Ecks,
obviously scientiofic undersatnding of what is happenning in the Oort cloud or beyond that is affecting this solar system is going to change rapidly.
I suppose that the nagging question is,
if there is a brown dwarf ,
with 20-50 earth masses,
or huge planet with 2-5 the size of Jupiter,
or many of them,
do they have stable nearly circular orbits?
or highly elliptical orbits like Sedna,
and if so,
what or who is to say that those orbits do not intersect within the solar system?

Most prominent among these, she says, is the fact that there are more observers in the Northern Hemisphere to discover comets than in the Southern Hemisphere, thus a number of long-period comets are probably escaping detection and analysis,
and the fact that the legendary PX supposedly blindsides us from the area of the south pole,
perhaps there is something to historical mythology of a returning large planet .
