Astronomers reject the idea of Nibiru, and have made efforts to inform the public that there is no threat to Earth. An orbit like that of Nibiru within our Solar System is inconsistent with celestial mechanics.
Essentials
David Morrison, NASA space scientist explains that after just one previous flyby of Earth, such as they claim happened in Sumerian times, Earth itself would no longer be in its current near circular orbit and would be likely to have lost its Moon. If Nibiru were a brown dwarf it would have even worse effects, as brown dwarfs are far more massive. Astronomer Mike Brown notes that if this object's orbit were as described, it would only have remained in the Solar System for about a million years before Jupiter expelled it, and, even if such a planet existed, its magnetic field would have no effect on Earth's.
In his rebuttal of Immanuel Velikovsky 's Worlds in Collision , which made the same claim that the Earth's rotation could be stopped and then restarted, Carl Sagan noted that, "the energy required to brake the Earth is not enough to melt it, although it would result in a noticeable increase in temperature: The oceans would [be] raised to the boiling point of water The Earth cannot do it by itself, because of the law of the conservation of angular momentum.
In a interview with the Discovery Channel , Mike Brown noted that, while it is not impossible that the Sun has a distant planetary companion, such an object would have to be lying very far from the observed regions of the Solar System to have no detectable gravitational effect on the other planets. At that speed, any object would be shot out of the Solar System, and then out of the Milky Way galaxy into intergalactic space.
One such accusation involves the IRAS infrared space observatory, launched in The satellite briefly made headlines due to an "unknown object" that was at first described as "possibly as large as the giant planet Jupiter and possibly so close to Earth that it would be part of this Solar System". Another accusation frequently made by websites predicting the collision is that the U. Its South Pole location was chosen due to the low-humidity environment, and there is no way an approaching object could be seen only from the South Pole. Another conspiracy claim regards a patch of missing data in Google Sky near the constellation of Orion, which has often been cited as evidence that Nibiru has been redacted.
However, the same region of sky can still be viewed by thousands of amateur astronomers. A scientist at Google said that the missing data is due to a glitch in the stitching software used to piece the images together. All are, in fact, names for other real, hypothetical or imaginary Solar System objects that bear little resemblance either to the planet described by Lieder or to Nibiru as described by Sitchin.
Lieder drew the name Planet X from the hypothetical planet once searched for by astronomers to account for discrepancies in the orbits of Uranus and Neptune. He concluded that they were being tugged by the gravity of another, more distant planet, which he called "Planet X". The discrepancies remained through to the s when the astronomer Robert Harrington put forward his hypothesis for an extra planet beyond Neptune with, as one example, a semi-major axis Six months before Harrington died of throat cancer [77] [78] in , astronomer Myles Standish showed that the supposed discrepancies in the planets' orbits were illusory, the product of overestimating the mass of Neptune.
This is frequently claimed to be an observation of 'Nibiru'. In , New Age author V. Rabolu wrote in Hercolubus or Red Planet that Barnard's star is actually a planet known to the ancients as Hercolubus, which purportedly came dangerously close to Earth in the past, destroying Atlantis , and will come close to Earth again. Barnard's star has been directly measured to be 5. In , Muller postulated that mass extinctions were not random, but appeared to occur in the fossil record with a loose periodicity that ranged from 26 to 34 million years.
He attributed this supposed pattern to a heretofore undetected companion to the Sun, either a dim red dwarf or a brown dwarf , lying in an elliptical, million-year orbit. This object, which he named Nemesis, would, once every 26 million years, pass through the Oort cloud , the shell of over a trillion icy objects believed to be the source of long-period comets that orbit at thousands of times Pluto's distance from the Sun.
Nemesis's gravity would then disturb the comets' orbits and send them into the inner Solar System, causing the Earth to be bombarded. However, to date no direct evidence of Nemesis has been found. Other people also confuse Nibiru with Sedna Sedna or Eris Eris , trans-Neptunian objects discovered by Mike Brown in and respectively.
Only slightly more massive than Pluto, [94] Eris has a well-determined orbit that never takes it closer to the Earth than 5. Others have tied it to Tyche , [98] the name proposed by John Matese and Daniel Whitmire of the University of Louisiana at Lafayette for an object they believe to be influencing the orbits of comets in the Oort cloud. Some associated Nibiru with Comet Elenin , [] a long-period comet discovered by Russian astronomer Leonid Elenin on December 10, Comet hysteria is not uncommon.

He demonstrated that its gravity would have caused noticeable changes in the orbit of Saturn years before its arrival in the inner Solar System. In August, , Comet Elenin began to disintegrate, [] [] and by the time of its closest approach in October the comet was undetected even by large ground-based telescopes. While a dim remnant did eventually return round the Sun, it was generally accepted to be a cloud of dust, rather than a solid object.
In March , astronomers Chad Trujillo and Scott Sheppard published a paper in Nature arguing that the apparent clustering of the arguments of perihelion of distant trans-Neptunian objects suggested the existence of a large trans-Neptunian planet. However, astronomers pointed out that this planet, if it exists, would have a perihelion closest approach to the Sun of roughly AU, or 30 billion km. In March , believers in the Nibiru cataclysm began to suggest that the month marked the true date for Nibiru's arrival and the destruction of Earth. The impact of the public fear of the Nibiru cataclysm has been especially felt by professional astronomers.
In , Mike Brown said that Nibiru was the most common pseudoscientific topic he was asked about. NASA frequently has to evaluate whether or not to respond to such claims, and the value of reassuring the public is outweighed by the risk of granting further exposure to a completely non-scientific idea. Morrison noted in a lecture recorded on FORA. A viral marketing campaign for Sony Pictures ' film , directed by Roland Emmerich , which depicts the end of the world in the year , featured a supposed warning from the "Institute for Human Continuity" that listed the arrival of Planet X as one of its doomsday scenarios.
