Those familiar with either the writings of Zecharia Sitchin or the current internet rantings about “the return of Planet X” are likely familiar with the word “nibiru”. According to self-proclaimed ancient languages scholar Zecharia Sitchin, the Sumerians knew of an extra planet beyond Pluto. This extra planet was called Nibiru. Sitchin goes on to claim that Nibiru passes through our solar system every 3600 years. Some believers in Sitchin’s theory also refer to Nibiru as “Planet X”, the name given to a planet that is allegedly located within our solar system but beyond Pluto. Adherents to the “returning Planet X hypothesis” believe the return of this wandering planet will bring cataclysmic consequences to earth.

Is Sitchin correct – Is Nibiru a 12th planet that passes through our solar system every 3600 years? Did the Sumerians know this? Unfortunately for Sitchin and his followers, the answer to each of these questions is no. But how do I know? The cuneiform record in such texts as the one on the left, the astronomical text known as MUL.APIN (The "Plough Star").

Readers can click here for a summary paper I wrote on the word nibiru in cuneiform texts. What follows draws from that paper and, in the case of the video, demonstrates the accuracy of my contention that there isn't a single text in the entire cuneiform record that:

• Has nibiru as a planet beyond Pluto
• Connects nibiru with the Anunnaki
• Has nibiru cycling through our solar system every 3600 years 

Here is a video that I created showing you where to find the leading dictionary of cuneiform words online (for free). Viewers can find that source and do what I do in the rest of the video: look up the entry for nibiru (spelled neberu in scholarly transliteration) and check to see if any of the above ideas are found in any Akkadian or Sumerian texts that mention nibiru. Spoiler: there aren't any -- but don't take my word for it. Look it up yourself.
