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, http://news.bbc.co.uk/1/hi/sci/tech/467572.stm 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. http://www.space.com/scienceastronom...ts_991014.html 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. ** Anita Cochran, astronomer and comet specialist at the University of Texas at Austin 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." ****************** In lieu of all the statements by Marsden on Sedna...

The Deep Impact spacecraft will launch in December 2004 and then encounter comet Tempel 1 on July 4, 2005.

More "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 .

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? ** Anita Cochran, astronomer and comet specialist at the University of Texas at Austin 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 . |

Hey Phil,
gee dont I get 3 strikes here at BABB? OK , I have 2 strikes. Better not strike out my first nite. Thanks for letting me post. In any case Phil, I was just wondering if these comments by the aforementiond scientists were of valid merit, and worthy of response here on your forum. It seemed to me to be all pretty bold statements,, Brown dwarves and all, or "***so-far unseen planet is several times bigger than the largest known planet in our Solar System, Jupiter." And why only one "unforeseen planet " ? "several times bigger than Jupiter" Like I saked earlier Phil, if there is something that large or massively gravitational out there, would it have a stable orbit, like Sedna supposedly has, or could it be what Sedna actually orbits towards in its unusual elliptical orbit, and all that "second foci point" binary star proposal, Or can we safely assume that it could also easily be a giant rogue planet , or even massive brown dwarf with another Sedna style orbit intersecting with the planetary alignments? with the huge comets Hale-Bopp and NEATV1, coming virtually one after the other, it is not hard to imagine that something bizarrely huge or massive could come by as well, with an entourage of NEATV1s as a predecessor. Every time these astronomy and physics Drs bring out more "speculations" derived from scientific analysis, on these huge outerplanets/brown dwarves, the more Sitchin and Velikovsky sound right on the money . |

"...how can you explain an object much more massive than Sedna avoiding detection? While it's technically possible, it's highly improbable for the reason I just gave." Well, obviously Marsden , Murray , and Matese believe it is hard to detect. Murray ***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." Matese "...2- to 3-Jupiter mass object orbiting some 2.3 trillion miles from the sun ***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. Dr. Matese´s theory...could the darkest corner of our solar system harbor a tenth planet ***or a 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.

Marsden "....There might still be something else out there causing this object´s peculiar orbit." "But even if it sent it into 76 A.U., when then is the aphelion 1,000 A.U. ? There is no way!

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." |

Well my physics isn't the best, but from a relative common sense approach to things, two points stand out in my mind.
1) No obvious effects on planatary orbits. If planet the size of the one you are talking entered into the inner solar system then there would be a lot of disturbance in the orbits of the planets already here. This means that their orbits would be greatly perturbed and far more elipitical than they are (Venus has an eccentricity of 0.0068 the least of all planets, Earth's is 0.0167, and Mars' is 0.093 still well under Pluto's of 0.250) Most of the Inner Planet's orbits are very circular showing very little devation, not what would have been predited under the above senario. Nothing I hve seen yet shows how such a planet could indeed enter the system without causing serious gravitational effects on planetary orbits, especially if it is supposed to have such serious effects on the Earth as some claim. 2) I would be serious surprised if a planet 20-50 times Earth's size (which by the way doesn't come near the size of a Brown Dwarf as that is only about size of Neptune to half the size of Saturn. In fact even a planet that is 5 times Jupiter's size desn't count as a Brown Dwarf as it is still to small by a magnitude of 100.) However having said that, Any planet that big would hve extreme proble with a radical comet-like orbit because of factors of momentum. You can't stop a plent the size of Jupiter on a dime, yet that is the physics that is being claimed in your theory. If a planet did follow such an orbit, the leaving orbit would be parabolic in shape and that would fire such a planet out of the system after one pass. Think about it this way. The planet's momentum has to be reduced to zero before it can be reversed. That means that for massive obects, such as planets, they has to travel a distance of almost equal distance past the sun as it arrives from. This means that unless it has a very narrow orbit that it can't pass through the solar system and because stable orbits need to have the Aphelion at least twice that of the Perihelion to prevent the planet's obit becoming Parabolic. That will result in any Planet of size at the most perhaps coming close to the outer planets, but nowhere near the inner ones. This means that even if such a planet does exist, it won't be a problem to us.

"Nothing I hve seen yet shows how such a planet could indeed enter the system without causing serious gravitational effects on planetary orbits, especially if it is supposed to have such serious effects on the Earth as some claim. " What about Van Flanderns collisional theory of Planet X causing the asteroid belt? "I would be serious surprised if a planet 20-50 times Earth's size (which by the way doesn't come near the size of a Brown Dwarf ..." the idea, was that it was a brown dwarf with **20-50 earth **masses, not size .Approximately the size of Jupiter , this would be actually, though Matese infers a brown dwarf of only 2-3 earth masses. "If a planet did follow such an orbit, the leaving orbit would be parabolic in shape and that would fire such a planet out of the system after one pass. " Well then explain Sednas orbit, why does it not just, "parabolically fire out of the system in one pass?' What about all the comets ?..... "That will result in any Planet of size at the most perhaps coming close to the outer planets, but nowhere near the inner ones." still again, what about van Flanderns asteroid belt formational events ? Sednas orbit works in your description, as an outer solar system influence, but Sednas existence alone has shown that radical elliptical orbits that were never before thought possible of planets are now very real. 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." * Then take into account huge comets like NEATV1, the cometary head almost twice the size of Jupiter, and all the controversy over its core size. Phil and Co. maintain the premise that NEATV1 had an inner core of very small proportions inside of the dirty snowball, McCanney and his crowd maintain it was the size of Mercury . I believe this as well, that NEATV1 was a planetary sized object in cometary form and motion. NEATV1 coming in from BEHIND the sun http://soho.nascom.nasa.gov/data/rea...18_0754_c3.gif |

By the way, I was talking about MASS with the Brown Dwarves. These have masses about 1/10th of our sun. Size from distance doesn't mean lot when it comes to planets as gravity is an affect of mass, not equator size. Neptune has a mass of about 17 Earths hence why I used it as a lower limit for your 20-50 Earth masses. Saturn has a mass of about 95 Earths which is why I used it as an upper limit. Jupiter has a mass of 315 Earths, and is still over 100 times smaller in mass than a Brown Dwarf. Matese might infer that a brown dwarf has only 2-3 Earth masses, but if he does, he's wrong because the term "Brown Dwarf" refers to a body about 1/10th of our sun's mass. If he doesn't understand the term, then he shouldn't use it. If his knowlegde of Astronomy is lacking in this area, one has to wonder where else he mkes such blatant mistakes. Quote:

"...perhaps there is something to historical mythology of a returning large planet ." Could there be something big and dark quietly orbiting our sun far beyond the known Solar System? Could be. But I don't see a single shred of convincing 'historical mythology' that even suggests such a situation. If, however, one insists on adding brown dwarves to the Solar system planetary lexicon based on cherry-picked myths and questionable translations of the same, one should also include mermaids in biology texts, and fund an expedition to Faery to obtain samples of unicorn horns. I submit that the evidence for either is *at least* as strong as that for 'Nibiru.' |

Now, if you ask me for evidence to support this of course I'll refer you to these astronomers who are professors at major accredited universities, and you'll say, "Considering their resumes, that's not surprising," and then I'll ask, "what about them? I don't know. And how do you see that affecting their "science," as it were?" |
