Planet X in the Solar System, is it really there?

In 1781, scientists predicted the existence of Planet X, a gas giant planet larger than Jupiter and inhabit the outer Solar System. The planet X existency allegation stems from the discovery of the Uranus. The planets have orbits typical, irregular. Scientists suspect that it might happen because of the large planet undiscovered.

Efforts to find Planet X was done. However, with more advanced telescopes, astronomers have not been able to prove its existence. Attempts to find a planet X actually yielded the discovery of Neptune in 1846 and Pluto in 1930. Both Neptune and Pluto can not be said to be wanted for planet X has a smaller mass than Jupiter. Planet X is estimated at four times the mass of Jupiter.

Although the evidence was never found, many people still believe in the existence of the mysterious planet. Its presence is associated with a tendency even asteroid hit Earth and helped to cause the extinction of the dinosaurs 65 million years ago.

Once again trying to prove the existence of the planet, Kevin Luhman, an astronomer at the University of Pennsylvania, did research with the NASA Wide-field Infrared Survey Explorer (WISE) instruments. While some people might expect there to be evidence of Planet X, the opposite happened.

Luhman through his research found no sign of planet X. Luhman can not find it in the image observations. "The outer solar system may not have a giant gas planet (Planet X) or a small star as the friend of Sun (Nemesis)," Luhman said as quoted by AFP on Monday, March 17, 2014. Luhman study results have been published in the Astrophysical Journal. Finding evidence of Planet X, Luhman and his team of research with WISE instrument actually found 3,525 stars and dwarfs. *** [EKA | FROM VARIOUS SOURCES | LIVESCIENCE]
