The Sumerian culture describes, according to some sources, a planet Nibiru (or Marduk) being the twelfth planet. Nibiru is thus a hypothetical 12th planet or Planet X. 12th Planet Nibiru, named from Sumerian astronomy, is supposedly the twelfth member in the solar system family of planets (which includes 10 planets, the sun, and the moon). Its collision with Tiamat, a planet that was between Mars and Jupiter, would have formed the planet Earth and the asteroid belt and comets. It is reported that Nibiru stands for "Planet of the Crossing". It was represented in antiquity by a cross and a winged disk. Pantheons According to some Nibiru is the supreme deity in the Sumerian and Babylonian pantheons. Though Nibiru is the god of 50 names and king of gods, according to others he is not related to Marduk in Babylonian mythology (Marduk being the a god of Babylon, who was inserted into the old creation epic). Books A suggestion in The 12th Planet by Zecharia Sitchin, who considered his proposal a serious theory. Sitchin's claims are generally considered pseudoscience by mainstream scientists and historians aware of the book. According to Zecharia Sitchin, Nibiru has an orbit around the sun of 3,600 Earth years. It is suggested that current astronomy points to the possibility that Nibiru is a brown dwarf or dark star rather than a planet. This has the implication that our solar system, like the majority in the known universe, is a binary star system; in other words, Earth has two suns with Nibiru being the second and less bright. According to Sitchin, Nibiru/Marduk's inhabitants called Anunnaki (Ningischzida) survived and afterward came to Earth. Sitchin says some sources speak about the same planet, possibly being a brown dwarf star and still orbiting the Sun with a perihelion passage some 3,600 years ago and assumed orbital period of about 3,600 to 3,760 years or 3,741 years. Sitchin attributes these figures to astronomers of the Maya civilization, but the supposed sources are unfamiliar to Mayanists. In a recently published book, titled 2012: Appointment With Marduk, Turkish writer/researcher Burak Eldem presents a new theory, suggesting a 3,661 years orbital period for the planet, and he claims a "return date" in the year 2012. According to Eldem's theory, 3,661 is one-seventh of 25,627, which is the total time span of "5 World Ages" according to Mayan Long Count Calendar system. The last orbital passage of Marduk, he adds, was in 1649 BC and caused great catastrophes on earth, including the Thera Eruption. Flaws Some suggest that the brown dwarf idea is fatally flawed in that a brown dwarf with a period of 3,760 years would be clearly evident through infrared and gravitational observations From http://en.wikipedia.org/wiki/Nibiru

Ok. The Planet Nibiru, was recently found on the outside of our solar system. In fact, it was moving and then suddenly stopped. When NASA sent a probe to see what it was, it moved, hence the other name given to it, The Thinking Fireball. Other names are The Crystal City and Rilo7. Now, i personally believe that NASA does not want anyone to really know about it, because if you search rilo7 or thinking fireball or the crystal city, you dare not find anything valid, unless it is on Wikipedia, which we all know, anyone can write in. So, what do you think about it?

It's a popular myth. There is absolutely no scientific evidence to support it's existence. If NASA did know of an additional planet in our solar system, not only would they NOT hide it, they would publicize the heck out of it. Discoveries like that are what keep them on the map, and keep the checks rolling in.

Do You Have Any Links From Nasa On This Object That Just Stopped Then Began Moving Again? As For NASA Not Hiding Something Such As This.. They Would, Think of It As.. If You Told Everyone in the World They Had One Day To Live Before Nukes Were Sent Off Everywhere.. It's Be Mass Catasrophe. Not That Everyone's Going To Die On This Date, But Not Everyone Has Studied This Scenario and It's Easily Possible For Everyone To Come Up With Their Own Solutions. Also, If the Polar Ice Caps Melt From Polar Shifts, and Antarctica Melts, Seeing As It's Set On Land, It's Going To Flood Into the Ocean Raising Sea Levels 15 Meters So Say Quite the Few Sources. That's I Believe 3.3 Feet a Meter? Which Would Come Out To Be 49.5 Feet. Plus With Such a Drastic Change, the Tsunamis Will Be Tremendous, Along With Earthquakes and the Such. I Believe It May Be a Brown Dwarf.. But As States Above, That Is True That It Would Probably Show Up Quite Easily. Also Though, Brown Dwarfs Give Off Self Light Rather Than Reflecting Light So Being AS Dim, and Although We Can View Them With Infrared View, It's Still Difficult To View All of Them. So There Could Possibly Be Something We're Just Missing. With Just About 5 Years Though, You Would Think It'd Be So Close That It'd Be Impossible To Miss It; and Whatever That Newly Found Planet Is Found Like Thre Times the Distance From the Sun To Pluto I Beleive (Would Have To Check Again For Accurate Facts) It's Only About the Size of Pluto and Has a Small Orbit. It Doesn't Even Orbit Within Our Inner Planets To Even the Smallest of an Extent. Hrm.. It's a Mystery. I'm a Believer Though.

Yes it does

Yes. NASA uses the books of Harry Porter as a reference for planet Nibiru. LOL. Pure fantasies. My 2 cents.
