Nibiru

From The Red Pill

Nibiru, to the Babylonians, was the celestial body associated with the god Marduk. The name is Akkadian and means 'crossing place' or 'place of transition'. In most Babylonian texts it is identified with the planet Jupiter. According to writers Zecharia Sitchin and Burak Eldem, Nibiru in Sumerian records referred to an undiscovered planet or Planet X.
