Firstly, though it is said that Nibiru is larger than Jupiter, let us be nice and just say that Nibiru is identical in mass to Jupiter- 1.8986*10^27 kilograms. If it were larger, things would be even worse for the Nibiru proponents.
Second, the mass of the sun is 1.9891*10^30 kilograms.
Now, let us think about how much force this would entail being applied between the sun and Nibiru at the perigee of Nibiru's orbit, which is about 1 AU (150 million km) in distance.
The formula used derive how much force two objects are applying on each other by gravity is F=G([m1*m2]/r^2), where G is the gravitational constant (6.67*10^-11) m^3 * kg^-1 * s^-2).
Below I will omit the units for the sake of clarity. The m^3 and the km cancel to produce kg/s with a difference to the exponents of -3 (in case you read the math below and were looking for the three missing digits).
So, let us plug in the numbers:
F=[6.67*10^-11 * ([1.8986*10^27] * [1.9891*10^30])]/(150,000,
That's 119520000000000000000000000000000000000000000 Newtons of force every second between Nibiru and the sun at its orbit.
But then you might ask, when objects slingshot around the sun, they move quite quickly, which is how they escape. After all, that is how comets escape, right?
Exactly right. Of course, comets do not have the added burden of being thousands of times the mass of our own planet, but that is exactly how they escape- they reach "escape velocity," or, the speed required to escape a gravity well.
So how fast would an object the size of Nibiru, moving in an elliptical orbit, be required to be traveling in order to escape the sun?
The formula for escape velocity is Vsec=[2*G*M/r]^1/2, or, the square root of [2*G*M/r] where G is the gravitational constant, M is the mass being dealt with, and r is the radius of a circle whose diameter is the distance between the objects.
Our G is 6.67*10^-11.
Our M is extracted from the N-M/kg from the first formula, so, 1.1952*10^44.
Our r is 1/2AU, so about 7.5*10^10 km.
This means that Nibiru's escape velocity must be 14,870,000 kilometers per second.
To put this utter absurdity into perspective, this is NEARLY SEVEN TIMES THE SPEED OF LIGHT! If Nibiru were ever travelling even a tiny fraction of that speed, tidal forces would tear it apart. Its wake would vaporize the inner planets. This is ridiculous. Abandon this foolish belief- it is debunked NOW.
Thank you, Ben. You have showed me why Nibiru would need to be traveling a great deal FASTER than I had originally calculated.
He is absolutely right: I misstated the distance of 1 AU (I had billions in my head where I should have had millions). Unfortunately for Ben, because the distance part of the equation is on the bottom side of the division bit of the Vsec formula, this means that I am DECREASING the radius of the circle, so I am INCREASING the necessary escape velocity by three more digits!!
Sorry Ben, that change doesn't mean reducing the final product by a factor of a thousand, it means increasing the pre-root Vsec by three digits. Thanks for editing my work for me, now I know that things are even worse for you than I thought.
Thanks, Ben, you have been VERY effective in showing why the Nibiru superstition is EVEN MORE IMPOSSIBLE!
IRAS was designed to look in the far-infrared, well past what our eyes see. At the time, no one was really sure what it would find. To everyone's surprise, several bright point sources were found that did not correspond to anything seen on optical images taken of the same areas. In the press conference, the two scientists said that these objects could be almost anything, from a tenth planet in our solar system to distant galaxies.
Guess which it turned out to be? Sure enough, much deeper images were taken, and some of the objects were found to be dense gas clouds in our own Galaxy, while others turned out to be very distant galaxies. In fact, these observations heralded the discovery of a new type of object: Ultra-luminous Infrared Galaxies (ULIRGs). These are galaxies in which there is a burst of stars being born. The cocoons of dust in which the stars are enshrouded generates copious infrared, which is what was detected by IRAS. They published these results in the prestigious Astrophysical Journal, and you can even read it yourself.

The escape velocity of Nibiru at perihelion (note that I didn't say "perigee", since this is the closest approach of an object to Earth) would be exactly the same as any other solar orbiting object.

Well, I don't know where this guy came up with that final figure, but that value for the escape velocity of Nibiru from the Sun's gravity well is absolute garbage. The only objects in the Universe that have escape velocities greater than the velocity of light are black holes, and that's at a distance within their event horizons. The escape velocity of Nibiru at perihelion (note that I didn't say "perigee", since this is the closest approach of an object to Earth) would be exactly the same as any other solar orbiting object.
What I have given to the Nibiru people this time is mathematical proof that a planet the size of Nibiru could never escape the gravity well of the sun on its previous passes on an orbit that close.
I hope this is my last comment on the Nibiru hoax, but questions like the above six keep coming in. Most of the entries on the Internet about Nibiru are false. Wikipedia has it correct when they write that "Nibiru is a name in Sumerian, Babylonian astrology associated with the god Marduk, generally accepted as referring to the planet Jupiter." The rest is a hoax, including all the "stuff" questioner #! found on the internet. Questioners #2 and #3 mention the astronomical observatory at the South Pole, but I assure you these astronomers are not looking at Nibiru. The Antarctic is a great place for astronomical infrared and short-wave-radio observations, and it also has the advantage that objects can be observed continuously without the interference of the day-night cycle. If the questioner really thinks that Nibiru is visible in the daytime in the southern hemisphere, they are very confused; this sort of statement is obviously false. Questioners #3 and #4 seem to think that the government would hide information about Nibiru and the catastrophe supposedly due in a few years, but I can't imagine why. My experience is, in fact, that sometimes parts of the government do just the opposite, as in the frequent references to various terrorist threats or warnings about driving accidents on long holiday weekends, which are no more dangerous than any other time. In any case, the job of NASA scientists is to discover and tell the truth! Questioner (5) asks if Nibiru is the same as Eris, and the answer is an emphatic no. This Nibiru hoax has been around for a decade, including predictions that Nibiru would pass close to Earth and cause a catastrophe about 5 years ago. (Guess what: it didn't happen!). Eris, in contrast, is one of several dwarf planets recently found by astronomers in the outer part of out solar system, all of them on normal orbits that will never bring them close to Earth. There is a good write-up on Eris in Wikipedia. Finally, Questioner (6) asks me to identify two pictures. I could perhaps do so if I knew the type of telescope and camera used and the scale of photos. Without that information, I can only guess that (if these photos are real) these might be images of a gas cloud (nebula) ejected by a star in its old age. They are obviously very distant, since we see stars in the foreground superposed on the nebula. Also, since the stars are the same, this object (if it is real) has not moved between the dates of the two photos. It is just crazy that anyone would claim that these are photos of a planet in our own solar system. Let me say once again that Nibiru is a hoax promoted by a cult; it does not exist, and it certainly poses no threat to us. It saddens me that people would be taken in by such nonsense. David Morrison

Nibiru IS Jupiter. It's the name the astronomers of the time, gave to a position in the sky that Jupiter had during the course of its transit. If I'm understanding this correctly, it would be the exact point where it crossed over from one half of the sky to the other, like a solstic or equinox, but in this case, referring to the planet Jupiter. It means "crossing" and was used specifically in babylonian astronomy texts to refer to that point in time when Jupiter was nibiru (crossing).

Yep. Now if he had said that every 3000+ years, Jupiter goes wacko and messes with the solar system, I'd be more inclined to believe him.
The Sumerians did not have telescopes, and only knew of 5 planets (7 if one counts the sun and moon), Mercury, Venus, Mars, Jupiter and Saturn. They did not know of Uranus, Neptune or Pluto as Sitchin claims. Of the planets that lay beyond Saturn (namely, Uranus, Neptune and Pluto) the ancients show no sign of having been aware of them. Uranus was only discovered and named in the post-telescope era by William Herschel in 1781. That goes doubly for Neptune or Pluto that lay beyond Uranus, and were discovered much later. None of those three planets show up on any known pre-Galilean sky charts.
