Is that alleged giant rocky planet actually Nibiru?

[Kenelm]

I'm sure most people here will have heard the recent reports postulating a giant rocky planet far beyond the orbit of Pluto, and immediately thought of Nibiru, if only to dismiss it straight away. I decided to check up on its vital statistics. If you type in the various details for the putative giant planet given in the 26 March New Scientist article here http://www.newscientist.com/article/dn25301-new-dwarf-planet-hints-at-giant-world-far-beyond-pluto.html#.Uz3iqLfjjct (such as an orbital radius of 250 AU and a mass 10 times that of the earth) into this handy Orbital period of a planet Based on Kepler's third law calculator here http://www.calctool.org/CALC/phys/astronomy/planet_orbit you get an orbital period for this supposed giant planet of 3,952 years, which is surprisingly close to Sitchin's claim of approximately 3,600 years for the orbital period of Nibiru.
