In the early 1990's, calculations by the United States Naval Observatory have confirmed the orbital perturbation exhibited by Uranus and Neptune, which Dr. Thomas C Van Flandern, an astronomer at the observatory, says could be explained by "a single undiscovered planet". He and a colleague, Dr. Robert Harrington, calculate that the 10th planet should be two to five times more massive than Earth and have a highly elliptical orbit that takes it some 5 billion miles beyond that of Pluto.

We know today that beyond the giant planets Jupiter and Saturn lie more major planets, Uranus and Neptune, and a small planet, Pluto. But such knowledge is quite recent. Uranus was discovered, through the use of improved telescopes, in 1781. Neptune was pinpointed by astronomers (guided by mathematical calculations) in 1846. It became evident that Neptune was being subjected to unknown gravitational pull, and in 1930 Pluto (was located). The latest advances in space imaging do not rely solely on orbital perturbations as the way for locating and identifying possible candidates for Planet X.

The 6,000 year old Sumerian descriptions of our solar system include one more planet they called "Nibiru", which means "Planet of the crossing".The descriptions of this planet by the Sumerians match precisely the specifications of "Planet X" (the Tenth Planet), which is currently being sought by astronomers in the depths of our own Solar System. Why has Planet X not been seen in recent times? Views from modern and ancient astronomy, which both suggest a highly elliptical, comet-like orbit, takes Planet X into the depths of space, well beyond the orbit of Pluto. We discovered Pluto with our telescopes just recently in 1930. Is it not possible that there are other forces at work on our solar  system besides the nine planets we know of? YES!!!! The Sumerian descriptions of Our Solar System are being confirmed with modern advances in science. This article will show actual diagrams from the Sumerian times and how the accuracy for describing the planets is overwhelming!
