“There could be a new ninth planet floating beyond the dark edges of our solar system, according to new research published in The Astronomical Journal from CalTech professors Mike Brown and Konstantin Batygin.
Brown and Batygin think they’ve found a celestial body that would meet all of the requirements for being classified as a planet. The researchers studied six small objects in the Kuiper belt and noticed their orbits funneled toward the sun in a very specific formation. The likelihood of this being a coincidence is slim to none. What researchers believe is that a new planet, unofficially dubbed “Planet X,” is pulling these objects into its orbit.”

NASA’s Director of Planetary Science, Jim Green, discusses the Jan. 20 Astronomical Journal science paper that points to the possibility of a new “Planet 9” in our solar system beyond Pluto, examining the scientific process and inviting you to have a front row seat to our exploration of the solar system.
The solar system appears to have a new ninth planet. Today, two scientists announced evidence that a body nearly the size of Neptune—but as yet unseen—orbits the sun every 15,000 years. During the solar system’s infancy 4.5 billion years ago, they say, the giant planet was knocked out of the planet-forming region near the sun. Slowed down by gas, the planet settled into a distant elliptical orbit, where it still lurks today.
The claim is the strongest yet in the centuries-long search for a “Planet X” beyond Neptune. The quest has been plagued by far-fetched claims and even outright quackery. But the new evidence comes from a pair of respected planetary scientists, Konstantin Batygin and Mike Brown of the California Institute of Technology (Caltech) in Pasadena, who prepared for the inevitable skepticism with detailed analyses of the orbits of other distant objects and months of computer simulations.
“If you say, ‘We have evidence for Planet X,’ almost any astronomer will say, ‘This again? These guys are clearly crazy.’ I would, too,” Brown says. “Why is this different? This is different because this time we’re right.”
