Astronomers Say Planet X Has Finally Been Discovered
Astronomers have announced that they have found evidence for the existence of the infamous ‘Planet X’ – which they say is around the size of Neptune. The new planet is the ninth addition to our solar system, which scientists say orbits the sun every 15,000 years. Sciencemag.org reports: 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.
