THE SEARCH FOR PLANET X
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 quiet 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).
In 1841, John Couch Adams began investigating the by then quite large residuals in the motion of Uranus. In 1845, Urbain Le Verrier started to investigate them, too. Adams presented two different solutions to the problem, assuming that the deviations were caused by the gravitation from an unknown planet.
* Sept 30, 1846 --- one week after the discovery of Neptune, Le Verrier declared that there may be still another unknown planet out there. On October 10, Neptune's large moon Triton was discovered, which yielded an easy way to accurately determine the mass of Neptune, which turned out to be 2% larger than expected from the perturbations upon Uranus.
* Another attempt to find a trans-Neptunian planet was done in 1877 by David Todd. He used a "graphical method", and despite the inconclusivenesses of the residuals of Uranus, he derived elements for a trans-Neptunian planet: mean distance 52 a.u., period 375 years, magnitude fainter than 13.
* In 1879, Camille Flammarion added another hint as to the existence of a planet beyond Neptune: the aphelia of periodic comets tend to cluster around the orbits of major planets. Jupiter has the greatest share of such comets, and Saturn, Uranus and Neptune also have a few each.
* Percival Lowell, most well known as a proponent for canals on Mars, built a private observatory in Flagstaff, Arizona. Lowell called his hypothetical planet Planet X, and performed several searches for it, without success. Lowell's first search for Planet X came to an end in 1909, but in 1913 he started a second search, with a new prediction of Planet X: epoch 1850-01-01, mean long 11.67 deg, perih. long 186, eccentricity 0.228, mean dist 47.5 a.u. long arc node 110.99 deg, inclination 7.30 deg, mass 1/21000 solar masses. Lowell and others searched in vain for this Planet X in 1913-1915. In 1915, Lowell published his theoretical results of Planet X. It is ironical that this very same year, 1915, two faint images of Pluto was recorded at Lowell observatory, although they were never recognized as such until after the discovery of Pluto (1930).
Recent 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. Richard 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

Something out there beyond the farthest reaches of the known solar system seems to be tugging at Uranus and Neptune. Some gravitational force keeps perturbing the two giant planets, causing irregularities in their orbits. The force suggests a presence far away and unseen, a large object that may be the long- sought Planet X. The last time a serious search of the skies was made it led to the discovery in 1930 of Pluto, the ninth planet. But the story begins more than a century before that, after the discovery of Uranus in 1781 by the English astronomer and musician William Herschel. Until then, the planetary system seemed to end with Saturn.Today, scientists accept theories concerning plate tectonics. There are articles and studies showing that, at one time, all of Earth continents were on one side of the planet. What the stories don't explore is the question, if all the continents were on one side, what was on the other? The other side has been described as a tremendous gap, matching the Sumerian story of how the Earth came about. The Sumerians said Earth was really half a planet called Tiamat, which broke up in a collision with Nibiru, [or Planet X].
The discovery of new planets has, in the last two hundred years, owed more to the science of mathematics than it has to the design of bigger and better telescopes. The unaccounted-for mathematical irregularities in the orbits of the outer planets have prompted astronomers to speculate upon the existence of a further, undiscovered planet. Astronomers are so certain of this planet's existence that they have already named it 'Planet X' - the Tenth Planet.
In 1982, NASA themselves officially recognized the possibility of Planet X, with an announcement that 'some kind of mystery object is really there - far beyond the outermost planets'. One year later, the newly launched IRAS (Infrared Astronomical Satellite) spotted a large mysterious object in the depths of space. The Washington Post summarized an interview with the chief IRAS scientist from JPL, California, as follows:
"A heavenly body possibly as large as the giant planet Jupiter and possibly so close to Earth that it would be part of this solar system has been found in the direction of the constellation Orion by an orbiting telescope... 'All I can tell you is that we don't know what it is', said Gerry Neugebauer, chief IRAS scientist.
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!
