What do Mesopotamian texts say about “nibiru”? Does what Zecharia Sitchin say about it demonstrable from the tablets themselves? Is it a planet beyond Pluto? Does it cycle through our solar system every 3600 years? Is it a planet inhabited by the Anunnaki?  Are the Anunnaki connected with it in any way?

In order, that would be: Plenty; no; no; no; no; and no.

Read about nibiru here in an old (2003) PDF of mine on the subject.
