Posted on 02/18/2009 4:45:00 PM PST by SunkenCiv
Planet X would be the most significant addition to the solar system since the discovery of Pluto... Any new object would have to be well clear of the Kuiper belt to qualify as a planet. Yet intriguingly, it is studies of the belt that have suggested the planet's existence. Some KBOs travel in extremely elongated orbits around the sun. Others have steep orbits almost at right angles to the orbits of all the major planets. "Those could be signs of perturbation from a massive distant object," says Robert Jedicke, a solar system scientist at the University of Hawaii... Over the past 20 years, huge swaths of the sky have been searched for slowly moving bodies, and well over 1000 KBOs found. But these wide-area surveys can spot only large, bright objects; longer-exposure surveys that can find smaller, dimmer objects cover only small areas of the sky. A Mars-sized object at a distance of, say, 100 AU would be so faint that it could easily have escaped detection. That could soon change. In December 2008, the first prototype of the Panoramic Survey Telescope and Rapid Response System (Pan-STARRS) was brought into service at the Haleakala observatory on Maui, Hawaii.

Yes there is, it is right between Planet Y and Planet Z!
Sorry, but I couldn’t resist.
When I said [still writing in 2002] that Planet X -- if there is one -- would be discovered by 2015, I didn't know about this, but hey, I'll take it. ;') The article sez that the total mass for the Kuiper Belt Objects identified thus far would, if combined, be about 20 per cent the mass of the Earth.The Hunt for Planet XJust over a year after the New Horizons' launch, it will... pick up enough velocity to reach Pluto, possibly as early as July 2015... In their new research, Melita and Brunini have explored three possible reasons for the Kuiper Cliff... The third possibility is that the region beyond was brushed clear by the gravity of Planet X... the KBO orbits they have investigated so far fit in best with the influence of a Planet X.

Wait a minute... wouldn’t it be between Planet W and Planet Y?
Nyah nyah. ;’)
I’m sorry, that was my evil liberal twin who made that post! LOL. keyboarding dyslexia or something.

Didn’t Alf call that object “Planet Dave?”
Interesting article. Isn’t there still some question as to whether Pluto should even be considered a planet?
The Man from Planet X!!
How is the search for our Sun’s twin, “Nemesis” going?
:’) Planetex sounds like a foot cream.
You know, you’re right.
Today is Pluto’s birthday BTW.
|"To Pluto And Far Beyond" By David H. Levy, Parade, January 15, 2006 -- We don't have a dictionary definition yet that includes all the contingencies. In the wake of the new discovery, however, the International Astronomical Union has set up a group to develop a workable definition of planet. For our part, in consultation with several experienced planetary astronomers, Parade offers this definition: A planet is a body large enough that, when it formed, it condensed under its own gravity to be shaped like a sphere. It orbits a star directly and is not a moon of another planet.|
Massive planet may lie beyond PlutoWriting in the issue of the Monthly Notices of the Royal Astronomical Society published on 11th October, Dr John Murray sets out a case for an object orbiting the Sun 32,000 times farther away than Earth. It would, however, be extremely faint and slow moving, and so would have escaped detection by present and previous searches for distant planets... The object would have to be at least as massive as Jupiter to create a gravitational disturbance large enough to give rise to the observed effect, but currently favoured theories of how the solar system formed cannot easily explain the presence of a large planet so far from the Sun. If it were ten times more massive than Jupiter, it would be more akin to a brown dwarf (the coolest kind of stellar object) than a planet, brighter, and more likely to have been detected already. So Dr Murray speculates that such an object, if it exists, will be planetary in nature and will have been captured into its present orbit since the solar system formed, even though the probability of such an event seems low on the basis of current knowledge.
Royal Astronomical Society News Release
October 7, 1999
“But lurking in the solar system’s dark recesses, rumour has it, is an unsighted world - Planet X, a frozen body perhaps as large as Mars, or even Earth.”
Rumor has it? Yes, “rumor” from ancient lores including an extensive description of PlanetX and its inhabitants and its past effects on the solar system and earth, courtesy of the Sumerians, the earliest known on earth. If “rumor” holds true, not only is there a planet X, we can expect a visit to the inner solar system in the not too distant future. Say about 2012. This would not be good news. Forget about buying gold.
Planet XWhat this means is that a planet of Earth's mass could exist undetected if it were more than a few 100 AU away, and even a Jupiter (300 Earth mass planet) could exist at distances only slightly greater. The sun could have a companion brown dwarf or even a star if far enough away! It's a nice thought but it will be very tough to do anything about it unless we are lucky. The Pan STARRS telescope now under development in Hawaii will provide the best constraints in the forseeable future... There is no convincing evidence for Planet X but "absence of evidence is not evidence of absence". Such an object could exist provided it is sufficiently far away.

Ancient astronomers wrote that “Planet X” was actually a binary system with a planet orbiting a brown dwarf.
Time will tell how accurate their historical descriptions were.
Really? Wow. That’s just dumb luck on my part.
Unless you’re talking about the cartoon character...
...Then on February 18 came the break: Planet X, predicted by Percival Lowell had been found. — Amir Alexander
“Why do we call hemorrhoids hemorrhoids and asteroids asteroids? Shouldn’t it be the other way around?” — Bob Schimmel
According to Sitchin — the inventor of Nibiru — the fictional planet is on a 3600 year orbit, which means it would have made its last pass through the inner Solar System in the late centuries BC.
Which ancient astronomers wrote that?
As for your second article, well...here is the original image. You judge for yourself. I can make all sorts of claims about images being inverted and mirrored, especially when my target audience knows NOTHING about spacecraft instruments.
His photo collage after that of "Planet X" peeking out from behind the sun shows a flawed understanding of orbital physics. Likely gleaned from hours of watching Star Trek and Star Wars in his parent's basement.
Nyah nyah. ;)
Better laugh now...in all Fairness, thuh fewchur dunna look brite...
Pluto was discovered, in part, out of the general search for Planet X. After the discovery of Neptune, astronomers noticed that it was not appearing where the laws of physics, which accurately described the orbits of the other planets, predicted. Uranus tended to be slightly off as well. This prompted the theory that something beyond Neptune was “tugging at it”. The discovery of Pluto was thought to have provided the answer, until astronomers quickly figured out that Pluto is not nearly massive enough to be the culprit. So the search for something larger beyond Neptune continues. I find the thought that the culprit may not be a planet but a brown dwarf or other burned out star orbiting the sun (or perhaps the other way around) very intriguing.
Nibiru is just one of many names for this planet from the Sumerian writings...it means “ferry” or “The planet of the crossing” or something like that. There may be multiple planets- multiple names. The concept of this explaining a connection to another solar system and another race... I find is fascinating.
art work from “Dark Star” aside, it’s an interesting subject to read about. The recent observatories established in Antarctica and now in Hawaii, plus other programs, may provide more hard data.
There certainly is a lot of commonality in the lore of the cultures of early earth, and in prophecy, and it does provide a fantastic wway to interpret some puzzling geological and other evidence. Has there been a polar reversal in the past- why? Will it happen again and why and when? Why are the bodies in the outer solar system warming -are they getting more geologically active? Are we?
Were we visited? Were we colonized? Were we “bred”?
This is one of those times when, if these is any credence to the descriptions of all of this as a cyclical event which will affects us again in our time, we will know one way or another soon enough. Meanwhile it’s interesting to BS about.
People are sure going to be speculating and reading more after the movie “2012” comes out this summer. Will this planet “X” become more visible by the same time this summer, as was written here? Maybe we’ll know this summer!
Meanwhile scientists are stockpiling those Noah’s arks with seeds- and maybe other stuff, too.
I was an astronomy buff, off and on, in my early teens (mid 1970s). The “Nemesis” hypothesis was very popular for explaining mass extinctions.
It went something like:
1. There are more binary star systems in the galaxy than single star systems.
2. The presence of a partner star to our Sun would cause a change in gravity affecting comets or larger asteroids as the two stars moved closer or farther apart.
3. Path changes in comets or large asteroids increase the possibility of collisions.
Now, this is what, 20 years before Hubble?

Probably find ya one of those very popular Obama-Head of State ....er....devices.
A planet sized, well, planet, might not have a really great effect on the earth when it comes ‘back’ into our solar system, eh?
I’m pretty sure there’s a Planet Claire. I heard she came from there. Like a Plymouth Satellite, faster than the speed of light... Planet Claire has pink air, all the trees are red. No one ever dies there, no one has a head.
These theories are awesome for finding flaws in science while partaking in the beverage of the evening. But as for verifiable science...well, I guess that’s TBD.
Planet Claire used to be married to a NY TV station owner?
Wouldn’t that be planet IX once again since Pluto got demoted?
Just think, if you had thought to say Planet X was proof that Darwin was a poopyhead, this would be prominently displayed in NEWS instead of CHAT.
And you could start the same thread ten times a day without objection.
Oy....someone else that wasted precious time on those books....
I was lucky enough to get to hear Clyde Tombaugh give a talk once—he was then in his 80s but still full of enthusiasm for astronomy. A memorable experience.
Yes, there is. I saw the files on t.v., The X Files.
The Nemesis idea came about from the combination of apparent periodicity of mass extinctions and the Alvarez model. David Raup was one of the early participants, and has a couple of books about Nemesis and mass extinction. Richard Muller here:
Ditto. There’s a school of thought that says that the Neptunian ephemeris can be better explained by dropping out a small number of observations, making the Planet X problem (quote) a psychological one (unquote). :’) That’s not my view, but hey, hardly anyone listens to me. ;’)
Planet Vulcan found?In fact, among the most recently discovered extrasolar planets is one that has been linked directly to Star Trek. Astronomers at the McDonald Observatory in Austin, Texas, announced earlier this month that they have detected a planet orbiting Epsilon Eridani, which is 10.5 light-years from Earth and the closest star yet showing evidence of a solar system. Epsilon Eridani has been identified in some Star Trek literature as the home of planet Vulcan.
8/31/2000 Science Roundup
from the Star Trek Official website
What makes this story more interesting from a Star Trek perspective is that the discovery was made by a team led by Dr. William Cochran of the University of Texas. It was Dr. Cochran's near-namesake, Dr. Zefram Cochrane, who was the first human to meet a member of the Vulcan species in "Star Trek: First Contact."
The planet found by the Texas team is a gas giant slightly larger than Jupiter with a stable orbit similar in radius to that of the asteroid belt in our own solar system. With the planet lying that distance from its star, the possibility is raised that Earth-like (Class M) planets could exist closer to Epsilon Eridani, in a zone Cochran said might be habitable...
Epsilon Eridani was identified as the Vulcan sun in the "Star Trek Spaceflight Chronology" published in 1980. However, other writings--including a letter from Gene Roddenberry and three astrophysicists to Sky & Telescope magazine in 1991--suggest that Eridani 40 is a likelier candidate for the honor. (It should be noted that the Vulcan sun has never been officially identified in the Star Trek series, so neither should be considered canon.)
About 50 extrasolar planets have been detected so far by astronomers measuring wobbles in the movement of their parent stars. No such planets have been observed directly, but NASA plans to launch two new space-based telescopes dedicated to the pursuit of Earth-like planets in 2013, in a project called the Terrestrial Planet Finder.
Planet Q is just south of Berkeley.
Blindsided: Planet X Passes in 2003
by Mark Hazlewood
Insiders from NASA speculate 2/3 of the population of the planet will perish during the coming pole-shift caused by the passage of Planet X in 2003. Another 2/3 of those that survive initially will pass away to starvation and exposure to the elements within 6 months. Every secretive government agency in the USA is fully aware of what is expected in 2003 and are readying themselves. The Vatican is fully abreast of what is expected. The public is not being warned and given their chance to prepare.
I’m a little jealous now. :’)
