Hallo Taurec,

Zu Sitchin hätte ich gerne eine zitierfähige Kritik, die sich nicht bei der Pseudoskeptikerorganisation GWUP findet.

wie wär's damit:
Michael S. Heiser (Ph.D., Hebrew Bible and Ancient Semitic Languages, Univ. of Wisconsin-Madison):
"The Myth of a Sumerian 12th Planet: 'Nibiru' According to the Cuneiform Sources"
http://www.sitchiniswrong.com/nibirunew.pdf

Here we have a specific Sumero-Akkadian text that says Nibiru is the name of Marduk. Below we’ll see that Marduk was the name of the planet Jupiter. Nibiru can’t be a planet beyond Pluto if it’s Jupiter. Nibiru-Marduk-Jupiter has something to do with a crossing place – that is, this astronomical body itself isn’t DOING the crossing, but marks or is positioned at a crossing point. This is another point of contradiction with Sitchin’s teachings, as he argues it is Nibiru that is mobile and “crosses” into the orbital paths of our solar system’s planets. The texts do not say this.

MULdAMAR.UD ne-bi-ri DISMULSAG.ME.GAR :
Nibiru is clearly called the star of Marduk, and is Jupiter. Oddly, here Nibiru “crosses the sky” and so appears mobile – but elsewhere it was a “fixed” star.
This again – despite the “mobility” cannot refer to a planet beyond Pluto for two reasons: (1) Nibiru is visible EVERY YEAR; (2) it is (again) either a star associated intimately with Jupiter or IS Jupiter.
How do we know the above phrasing refers to Jupiter? Because MUL.APIN catalogues the paths of the known planets (five, plus sun and moon as planets, for seven).

Summation to This Point:
What do the cuneiform texts tell us about Nibiru – particularly in contradiction to Zecharia Sitchin? Here’s the list:
1) Nibiru is called a star.
2) Nibiru is called a planet – nearly always Jupiter-Marduk, but once Mercury, and never anything beyond Pluto or the known planets.
3) The Sumerians, by their own records, knew of only five planets (and accepted the sun and moon as planets).
4) Nibiru is never mentioned in any respect with the Anunnaki; it is never said to have been or be inhabited.
5) Nibiru is both a “fixed star” in some relationship to constellations (whether a member or just in proximity is unknown) that “holds” them in their courses, but is also described as “changing position” and “crossing” the sky at times.
6) Nibiru was seen every year, which demolishes Sitchin’s view of a 3600 year cycle for it.

Die m.E. beste Deutung zu Nibiru findet sich hier:
Izabela Zbikowska: "Discovery of Planets Reflected in Cuneiform Religious Texts: Jupiter and First Zodiacal Concepts"

"...Analyzing this theological layer we look for references in religious texts, where we can find characterizations of gods personificating a given planet and determine an approximate time of its discovery (on the analogy of the time of worship). The best example here may be Jupiter (Babylonian Nibiru), since the Old-Babylonian period worshipped as celestial personification of the national god of Babylonia: Marduk. With Jupiter-Nibiru appears lumasu, a term very often discussed in assyriology, which -- as I want to show it here -- is evidence of first zodiacal concepts, inspired by Jupiter's movement and its sidereal period."

Grob vereinfachend und verkürzt: Nibiru = Jupiter, der in 12 Jahren die in 12 Abschnitte unterteilte Bahn durchläuft, der auch die anderen Planeten folgen (“Nibiru is his [marduk’s in context] star, which he made appear in the heavens . . . [130-131] The stars of heaven, let him [Nibiru] set their course; let him shepherd all the gods like sheep.”), sie nach Norden und Süden (wechselnde ekliptikale Breite) kreuzend (“let Nibiru be the holder of the crossing place of the heaven and of the earth”).
