Planet X One of the Great Mysteries of Astronomy or a Great Cover-Up?
It is one of the great mysteries of astronomy – a giant body, believed to lie somewhere beyond the orbit of Pluto, ’Planet X’, Nemesis or Tyche, it is believed that this mysterious large planet or small star might periodically pass through outer comets, sending them flying towards Earth and causing mass extinction.
According to a NASA news release, “no object the size of Saturn or larger exists out to a distance of 10,000 astronomical units (AU), and no object larger than Jupiter exists out to 26,000 AU. One astronomical unit equals 93 million miles. Earth is 1 AU, and Pluto about 40 AU, from the sun.” The study is published in The Astrophysical Journal.
However, researchers today admitted it may not exist after an exhaustive search of hundreds of millions of objects. ’The outer solar system probably does not contain a large gas giant planet, or a small, companion star,’ said Kevin Luhman of the Center for Exoplanets and Habitable Worlds at Penn State University, University Park, Pa., author of a paper in the Astrophysical Journal describing the results.
However, the team admit their research was not wasted – and say they found several thousand new residents in our sun’s ‘backyard,’ consisting of stars and cool bodies called brown dwarfs. ’Neighboring star systems that have been hiding in plain sight just jump out in the WISE data,’ said Ned Wright of the University of California, Los Angeles, the principal investigator of the mission.
