According to a study titled "Extreme Trans-Neptunian Objects" (ETNOs), which published in the journal Monthly Notices of the Royal Astronomical Society Letters, at least two planets with a size larger than Earth, thought to be hiding in our solar system, precisely behind Pluto.
Planet X and Planet Y, so the two giants was named were the two of 13 extreme objects beyond Neptune's orbit trajectory. If these findings can be verified, it will change the general knowledge about our solar system that says there is no other planet beyond Neptune.

Researchers at the Complutense University of Madrid have found some strange patterns in the rocky objects around Pluto. (Picture from: http://adf.ly/1XORZX)|
"The exact number we do not know, because of the very limited data, but our calculations show that there are at least two planets, and probably more, within our solar system," said Carlos de la Fuente Marcos, a scientist from the University of Madrid, which is engaged in that research.
According to the theory, the objects were supposed have a distance just 150 astronomical units from the Sun and the tilt of 0 degrees. The Earth's distance from the Sun is equal to 1 astronomical unit.
