		<description>in answer to  92, (dustin Says) such a &#039;counter-Earth&#039; planet is impossible 
I am aware of such a planet being used in SF, (Gor beung the famous example) but if such a planet existed it would have been discovered Centuries ago,  as Earth&#039;s orbit is lightly eccentric (not as eccentric as Mars&#039; but more eccentric than Venus&#039;) so your hypothetical planet would at times be moving faster or slower than Earth  so it would become visible as a bright naked eye object at total eclipses.
Also such a planet would cause perubations on other Planets and Spacecraft. Moreover the situation of two similar sized planets in the same orbit would be inherently unstable unless they are in the same orbit 60 degrees apart. 
So it is very likely that over the age of the Solar system that the two planets would inevitably collide.</description>

		<description>I believe that there is a planet in the same ring like Earth named Peramonia and has life on that planet. I don&#039;t know if they think we exsist but it is best to not to attack that planet to prevent war or we the planet might not exsist. But I wil find that planet some day no matter how long it takes.</description>

		<description>I think there can be because like,
there are TONS of other galaxies like TRILLIONS of them
so like 973659372992592051853959358 planets could exsist.
and what are the chances of any other sign of life.
i dunno maybe 8732543626 of the planets could have life right??
*not very scientific with no research*</description>

		<description>i think it is kinda of cool but i really need to know what is a sunspot???????

and how is it kool if another solar system combines with our solar system????

that would be big trouble!!!!</description>

		<description>You said: &quot;No, I’m not talking Nibiru or any of that other nonsense (and it is nonsense), &quot;

Just because you cannot conceive of something that the Sumerian, Akkadian and Nineva civilizations believed in, Does Not Make You Correct in calling it &quot;nonsense,&quot; and Disqualifies you from Being a Scientist. Science is based on Nothing more or Less than &quot;Hypothesis&quot;, which is defined as an &quot;Educated GUESS&quot;. There is NO SUCH THING as FACT in Science, it is ALL a Guess, educated GUESS, yes, but that is Still a Guess, since you CANNOT Disprove it.......A Lack of a planet like Nibiru, from what you or any other Astronomer can see is NOT proof that it does not Exist. It ONLY means you have not seen it.

Science &quot;Facts&quot; change faster than apparently your intellect does.

Now, IF we ever have the technology to Completely Map the Solar System, which we apparently DO NOT, since you are Just now finding this planet, NEAR US (that is LESS than a Light-Year away), and considering how many Planets have been FOUND in Other Solar Systems MANY Light Years Away from here, PROVES that you Cannot Know for Sure that Nibiru does not exist. Yet IF we ever have the Technology to Map the WHOLE Solar Syatem, Then, and ONLY THEN, can you say Nibiru does not exist.

The Sumerians Sure Knew that the Earth Revolved Around the Sun, THOUSANDS of Year Before Galileo. They Even know that we had 9 Planets (and Yes, Pluto IS a Full-Planet, no matter what some committee has decided, Pluto sure doesn&#039;t know the difference).

Now, &quot;I&quot; have just PROVEN how Little you KNOW about Science by the FACT that you have just now found this planet, even though over the past few years Literally Hundreds of Planets More than 10 Light-years away had already been found.

How SAD it is that YOU cannot Conceive that there is More out there, and that you have CLOSED your Intellect to the Possibilities of the Universe.

Save us ALL the Trouble and Leave the Field of Science while you still have Some Shred of Dignity left.

Personally, I DO NOT Believe in Nibiru, but I refuse to denounce it out of hand until it can be Proven one way or the other, and we CANNOT prove it one way or another....YET!!!!</description>

		<description>I am not suggesting anything here, but there seem to be a fair bit of science minded folks here who might be able to answer a question I have.  I honestly don&#039;t put any stock in the whole Nibiru thing, it seems doubtful, and that&#039;s being generous.  But while reading some of the comments it occurred to me that I recall reading about how it is more difficult to view objects in our own galaxy because our view is obstructed by other galactic objects and such.  I suppose I&#039;m just assuming that the same problem could, in some sense, occur with viewing objects in our own solar system as well.  With that in mind, suppose there were a planet roughly the same size as Earth at roughly the same distance from the sun, that had an identical or very similar orbital period, and which was on the exact opposite side of the sun.  Assuming, for the above reason, that we would be unable to see it directly, what other methods would we have for detecting it.  I&#039;m guessing the effects of its gravity would be one of the ways.  If that&#039;s the case, how accurately is gravity accounted for in our solar system.  Meaning, is there any serious disparity between calculated an observed movement of things moving through the solar system?  I&#039;m just curious, if anyone has any insight here.

		<content:encoded><![CDATA[<p>I am not suggesting anything here, but there seem to be a fair bit of science minded folks here who might be able to answer a question I have.  I honestly don&#8217;t put any stock in the whole Nibiru thing, it seems doubtful, and that&#8217;s being generous.  But while reading some of the comments it occurred to me that I recall reading about how it is more difficult to view objects in our own galaxy because our view is obstructed by other galactic objects and such.  I suppose I&#8217;m just assuming that the same problem could, in some sense, occur with viewing objects in our own solar system as well.  With that in mind, suppose there were a planet roughly the same size as Earth at roughly the same distance from the sun, that had an identical or very similar orbital period, and which was on the exact opposite side of the sun.  Assuming, for the above reason, that we would be unable to see it directly, what other methods would we have for detecting it.  I&#8217;m guessing the effects of its gravity would be one of the ways.  If that&#8217;s the case, how accurately is gravity accounted for in our solar system.  Meaning, is there any serious disparity between calculated an observed movement of things moving through the solar system?  I&#8217;m just curious, if anyone has any insight here.<br />
Thanks</p>

Although I appreciate the fact that you later say that you keep an open mind, this statement hardly sounds like that. So I have to ask you, how can you be getting tired of something that frankly isn’t happening. I’ll tell you what I get tired of… people coming here time and time again and railing about how we speak about ANYTHING being “100% fact” or “absolute truth”. That might be the single most maddening thing I here form the complainers. I hear it all the flippin time and yet having been a loyal reader for many years I can tell you that I have almost NEVER observed that happening.

I’m not going to get into yet another discussion of “Theory vs. Fact”, because it’s been discussed ad nauseum on this site. Please do some reading and research on the difference between the two and the difference between “everyday theory” and “scientific theory”.

Now, to address your point that I quoted above, it’s really NOT *simply* theory and educated guess work. These people have a huge amount of data to draw from, and are really not just simply guessing. It’s not like you’re holding a card behind your back and they are blindly guessing “3 of diamonds”. More accurately, it’s like they watched you discard every other card in the deck, have knowledge of how many cards you started with, and based on that evidence, can guess what card that is despite not *actually* having seen it. It’s logical and educated theories and conclusions based on a preponderance of evidence and observation. It’s not just a shot in the dark. Give the scientists who spend their careers on researching these issues a *bit* more credit than that… please.

(/rant)

Counter rant:
1.  I see theories passed off as certainty here (almost any time someone says something flat doesn&#039;t exist, since you can&#039;t really prove that something DOESN&#039;T exist).
2.  Those theories change from time to time as we get more data.
3.  You open a new pack of standard playing cards, and discard all but one.  I know exactly what you are holding, and there is no reason to change my &#039;theory.&#039;  While it is not impossible that your deck is a mistake and has two copies of the 3 of diamonds, I would not bet that way.  Your analogy implies a certainty that just isn&#039;t there.  Find two reputable experts in any scientific field who disagree with each other on a key point.  That is plenty of room for doubt.  &quot;We all agree that x happened, but we do not agree HOW it happened&quot; is a LOT of room for doubt, especially when each group can &#039;prove&#039; the other group&#039;s version is impossible.  This would indicate that we haven&#039;t seen enough of the cards to say it is a 3 of diamonds, though we might be able to say it is a diamond, or even a 3 in some cases.</description>

		<description>I saw something on the science channel the other day where, in working out the age of the craters on the lunar surface, someone came up with the theory that earth may have formed outside the asteroid belt and later moved in.   I wasn&#039;t able to catch all of it, but I seem to recall that the idea involved the young Earth&#039;s orbit decaying over time due to the combined gravity of Jupiter and Saturn.  This would imply that the Earth, or at least the moon, was formed somewhere further out than the asterid belt, as the passage through the belt is said to be the cause of the many craters on the moon dating to the same time.

I also read in a newspaper that one theory for the formation of the moon was that Earth got hit by something about the size of Mars early in its formation (which would mean it and the moon very likely moved together if both theories are correct, and I am not saying they are).

So, a 9th planet (since Pluto got the pink slip) at some monstrous distance may have formed much closer and then moved for whatever reason.  If there really were cue balls the size of Mars with the solar system was new, I&#039;d imagine they could move more than an eight ball.

Perhaps the heat from such a collision could be stored in crystals using perpetual motion magnet machines and the people of...Niribu (or whatever that planet is called) are using it to keep their amtosphere from freezing solid.  (Note this last paragraph did not receive a full ration of seriousness before being commited to the post)</description>

[[&lt;i&gt;To think our sun does not have an equally sized dark star orbiting it is nuts.&lt;/i&gt;]]

Our sun does not have an equally sized dark star orbiting it.

[[&lt;i&gt; That would mean our galaxy, in the entire universe, is the only one that does not have this feature.&lt;/i&gt;]]

You seem to be using &quot;galaxy&quot; to mean &quot;solar system.&quot;  The galaxy is the system of several hundred billion stars, in a multi-armed spiral 100,000 light-years across, that our solar system is a part of.  And if you mean &quot;solar system,&quot; please note that around a fifth of stars are actually single.  Not all stars are binary or multiple.

[[&lt;i&gt; I believe as we start to journey further past pluto(yes i still consider it a planet. It is the same size as Mercury and that’s still a planet.)&lt;/i&gt;]]

Pluto is considerably smaller than Mercury.  Mercury is about 0.055 Earth masses, Pluto more like 0.0022.

[[&lt;i&gt; we will discover our galaxy is much the same as all the others. Has any one ever wondered why near extinction events are nearly a set time apart?&lt;/i&gt;]]

Are you referring to Raup and Sepkoski&#039;s 1980s-era theory that there was a 26-million-year periodicity in mass extinctions?  I think they&#039;ve kind of dropped pursuing that one; it didn&#039;t work out when they checked.</description>

		<description>rp,

I believe the perturbations of Neptune they were trying to solve were subsequently shown to be spurious.  I.e., they found Pluto because of bad data.

  Makes you think, doesn&#039;t it?
  Push the car...</description>
