Nibiru is also reffered as one of these names you may have heard
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. In 1894, Bostonian astronomer Percival Lowell became convinced that the planets Uranus and Neptune had slight discrepancies in their orbits. He concluded that they were being tugged by the gravity of another, more distant planet, which he called “Planet X”. However, nearly a century of searching failed to turn up any evidence for such an object (Pluto was initially believed to be Planet X, but was later determined to be too small). In 1992, astronomer Myles Standish showed that the supposed discrepancies in the planets’ orbits were illusory, the product of overestimating the mass of Neptune. Today astronomers accept that Planet X, at least as originally defined, does not exist.
In 1999, New Age author V. M. 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.Lieder subsequently used Rabolu’s ideas to bolster her claims.
Barnard’s star has been directly measured to be 5.98 ± 0.003 light years (56.6 Pm) from Earth . While it is approaching Earth, Barnard’s Star will not make its closest approach to the Sun until around 11,700 AD, when it will approach to within some 3.8 light-years. This is only slightly closer than the closest star to the Sun (Proxima Centauri) lies today.
Believers in Planet X/Nibiru have often confused it with Nemesis,a hypothetical star first proposed by physicist Richard A. Muller. In 1984, 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, 26-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.Though the idea of Nemesis appears similar to the Nibiru cataclysm, they are, in fact, very different, as Nemesis, if it existed, would have an orbital period thousands of times longer, and would never come near Earth itself.
Sedna or Eris
Still others confuse Nibiru with Sedna (90377 Sedna) or Eris (136199 Eris), trans-Neptunian objects discovered by Mike Brown in 2003 and 2005 respectively. However, despite having been described as a “tenth planet” in an early NASA press release, Eris (then known only as 2003 UB313) is now classified as a dwarf planet. Only slightly more massive than Pluto, Eris has a well-determined orbit that never takes it closer to the Earth than 5.5 billion km. Sedna is slightly smaller than Pluto, and never comes closer to Earth than 11.4 billion km. Mike Brown believes the confusion results from both the real Sedna and the imaginary Nibiru having extremely elliptical orbits.
Others have tied it to Tyche, 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. In February, 2011, Whitmire and his colleagues took their hypothesis to the public in an article in The Independent, in which they named the object “Tyche” and claimed that evidence for its existence would be found once data from the WISE infrared telescope was collated, leading to a spike in calls to astronomers. The name, after the “good sister” of the Greek goddess Nemesis, was chosen to distinguish it from the similar Nemesis hypothesis as, unlike Nemesis, Matese and Whitmire do not believe that their object poses a threat to Earth. Also, this object, if it exists, would, like Nemesis, have an orbit hundreds of times longer than that proposed for Nibiru, and never come near the inner Solar System. In March 2014, NASA announced that the WISE survey had ruled out the existence of Tyche as its proponents had defined it.
Some associated Nibiru with Comet Elenin, a long-period comet discovered by Russian astronomer Leonid Elenin on December 10, 2010. On October 16, 2011, Elenin made its closest approach to the Earth at a distance of 0.2338 AU (34,980,000 km; 21,730,000 mi), which is slightly closer than the planet Venus. Nevertheless, in the leadup to its closest approach, claims spread on conspiracy websites concluded that it was on a collision course, that it was as large as Jupiter or even a brown dwarf, and even that the name of the discoverer, Leonid Elenin, was in fact code for ELE, or an Extinction Level Event.
Although the sizes of comets are difficult to determine without close observation, Comet Elenin is likely to be less than 10 km in diameter.Elenin himself estimates that the comet nucleus is roughly 3–4 km in diameter. This would make it millions of times smaller than the supposed Nibiru. Comet hysteria is not uncommon. Attempts have been made to correlate Elenin’s alignments with the 2011 Japan earthquake, the 2010 Canterbury earthquake, and 2010 Chile earthquake; however, even discounting Elenin’s tiny size, earthquakes are driven by forces within the earth, and cannot be triggered by the passage of nearby objects. In 2011, Leonid Elenin ran a simulation on his blog in which he increased the mass of the comet to that of a brown dwarf (0.05 solar masses). 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, 2011, Comet Elenin began to disintegrate, and by the time of its closest approach in October 2011 the comet was undetected even by large ground-based telescopes.
On 21 September 2012, Vitali Nevski and Artyom Novichonok, using the International Scientific Optical Network of telescopes (ISON), discovered the comet C/2012 S1, popularly known as “Comet ISON”. Its orbit was expected to take it within 0.429 AU (64,200,000 km; 39,900,000 mi) of Earth on 26 December 2013.Nonetheless, believers tied it to the Nibiru cataclysm, claiming it would hit the Earth on that date, or that it would fragment and pieces of it would hit the Earth. Images of the “fragments” of the comet circulating on the Internet were shown to be camera artifacts. On April 30, 2013, the Hubble Space Telescope took three pictures of the comet over the course of 12 hours, which were published as a composite in Hubble’s archives. This led to speculation on conspiracy sites that the comet had split into 3 pieces, or even that it was a UFO. After ISON passed perihelion on 28 November, it rapidly began to fade, leaving many to suspect that it had been destroyed as it passed the Sun. 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.On 2 December 2013, the CIOC (NASA Comet ISON Observing Campaign) officially announced that Comet ISON had fully disintegrated. The Hubble Space Telescope failed to detect fragments of ISON on 18 December 2013. On 8 May 2014, a detailed examination of the comet disintegration was published, suggesting that the comet fully disintegrated hours before perihelion.
In March 2014, 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. On January 20, 2016, Mike Brown and Konstantin Batygin announced that they had corroborated Trujillo and Sheppard’s findings, and that they believed the planet, which they dubbed “Planet Nine”, would have a mass roughly ten times that of the Earth, and a semimajor axis of approximately 400–1500 AU (60–225 billion km). Believers in Nibiru and the Nibiru cataclysm immediately argued that this constituted evidence for their claims. However, astronomers pointed out that this planet, if it exists, would have a perihelion (closest approach to the Sun) of roughly 200 AU, or 30 billion km.
In March 2016, believers in the Nibiru cataclysm began to suggest that the month marked the true date for Nibiru’s arrival and the destruction of Earth. That same month, the Monthly Notices of the Royal Astronomical Society published a paper by Daniel Whitmire (who had proposed the existence of Tyche) in which he reconsidered a modified version of the Nemesis model he had first proposed in 1985 in light of recent speculations concerning the possibility of a trans-Neptunian planet. The hypothesis argues that an object far closer to the Sun than Nemesis could have a similar effect if its orbit precessed at a rate thousands of times slower than its actual speed, which would mean it might only interact with the Kuiper belt every 27 million years, potentially sending comets into the inner Solar System and triggering mass extinctions. However, the paper had been initially published online in November 2015, before Brown and Batygin went public with Planet Nine, and concerns a different object far closer to the Sun (100 AU vs. ~600 AU); Planet Nine, if it exists, is too far away, says Brown, to have such an effect on the Kuiper belt. Nonetheless, an article in the British tabloid The Sun (later republished in the New York Post) conflated the three ideas of Nibiru, Planet Nine, and Whitmire’s planet to suggest that not only had Planet Nine been found, but that it would collide with Earth at the end of April, which resulted in Batygin receiving a spike in panicked calls.
