It might be best not to waste effort on putting up Christmas decorations around the house this year - or ever at all - as reports claim that the Earth will be destroyed on December.

Previous reports claimed that the world would end on both September 28 before another instance on October 7 - which clearly was false since we're all still alive right now.

"A rogue planet known in ancient times as Nibiru, The Destroyer, Wormwood, The Frightener, the Terrible Comet, Hercolubus and various other names, is headed toward Planet Earth once again, and has already begun to spawn a series of global catastrophes. In modern times, this dangerous celestial body has been known by the name of Planet X."

According to Unilad, the wandering planet of Nibiru has already been predicted to collide with Earth several times in the past. It's most likely been popularly heard from when the "Mayan apocalypse" was supposedly coming.

Author of UFO Investigations Manual Nigel Watson also quoted Zcharia Sitchin's astronomical theories, who originally said that Nibiru lives beyond Neptune, and visits this part of the Solar System - between Jupiter and Mars -- every 3,600 years:

"He [Zcharia Sitchin] claims that Nibiru collided with a planet called Tiamat that was situated between Mars and Jupiter. The result was the creation of the asteroid belt and planet Earth."

The theories seem far-fetched, but Before It's News provides additional background with regard to the reports:

"The planet NIBIRU revolves around Nemesis (WISE J104915.57-531906.1B), a dark subdwarf star more massive than Jupiter. Nemesis nears our Sun, at the KUIPER BELT, 48 Astronomical Units from Earth, every 10,800 Earth years. Nibiru circles Nemesis but did not orbit our sun."
