NASA scientists detect ROGUE planet that caused ‘DEVASTATING assault on solar system’

The solar system is currently made up of four planets of primarily silicate rocks or metals, these include Mercury, Venus, Earth and Mars. These planets have a solid surface, making them substantially different from the larger “gas giant planets”, which are composed mostly of some combination of hydrogen, helium, and water existing in various physical states. However, NASA scientists John Chambers and Jack Lissauer have theorised a similar fifth planet once existed between Mars and the asteroid belt.
