"Pioneer 10, mankind's first emissary to the space beyond our solar system, is resuming a mission of galactic sleuthing in search of a mysterious Planet X."

"Pioneer 10, the little spacecraft that won’t quit, is still searching for a 10th planet five years after leaving the known solar system and 16 years after leaving the launch pad, NASA scientists said Monday.
Disturbances in the orbits of Neptune and Uranus suggest that a mysterious Planet X may be orbiting beyond Pluto, John D. Anderson of NASA’s Jet Propulsion Laboratory said as NASA observed the fifth anniversary of Pioneer 10′s dash past Pluto’s orbit."

"The 1987 New Science and Invention Encyclopedia, Volume 18 SHEE-SPAC
In a section on space probes, the encyclopedia shows the paths of the two Pioneer probes were to ‘triangulate’ on the gravitational affects. It shows the Earth, the Sun, a dead star (at 50 billion miles or 538 AU) and a tenth planet (at 4.7 billion miles or 50 AU)."

"the infrared astronomical satellite (IRAS), circling in a polar orbit 560 miles from the Earth, detected heat from** an object about 50 billion miles away** that is now the subject of intense speculation."

"A NASA scientist insists a 10th planet may be orbiting the sun even though two space probes have not been able to find any trace of it in the dim outer reaches of the solar system."

"Using the Pioneer 10 Space Probe, they found the celestial body, which they called the 10th Planet. It's also been called Planet X and Wormwood. They've been tracking it ever since.
In 1985, there was another classified briefing at which they discussed violently rising ocean levels and abrupt climate change. The Navy has promoted the Arkansas/Missouri Ozarks as being one of the safe areas, and many Navy people have since moved to that region.
The Supervising Astronomer of U.S. Naval Observatory, Dr. Robert Harrington (now deceased) was interviewed in his Washington D.C. office (when?), in his official capacity. During the 10 minute interview, he talks about the 10th Planet, describing it as being 3 to 5 times larger than earth, with a far more dense core of iron/nickel."

"Pioneer Carries Message Across the Stars"

"“Daniel frequently describes a large star that will approach the Earth and though it will not hit the planet, it will cause great damage,” Rabbi Samuel said. “Scientists have never seen anything like this so they don’t know what to expect."

"The Sun’s binary companion (Nemesis) is thought to exist ever since the first launch of the early Pioneer 10 and 11 spacecrafts which detected the sun’s binary (dead) twin, a failed star around 50 billion miles away from the known solar system. Another object that was detected by the Pioneer spacecrafts and later by IRAS satellite in 1983 was around 4.7 billion miles away, a huge red gaseous object, in a highly elliptical orbit, too close to the solar system that it had to be part of it, it was suggested by the scientists. This celestial body was found in the same direction as of the Binary Companion of the Sun (dead star; Nemesis). Soon thereafter media pointed out that it was a mistake, that no celestial body was found. This object at the distance of 4.7 billion miles is also known as the Dwarf Star or Planet X in modern science, ancient Sumerians called it Nibiru, and in ancient Egyptian civilization it was known as the Destroyer Star."

"Variously called Nibiru, Planet X and Wormwood, the incoming behemoth is allegedly predicted in the Bible."

"Nibiru is a hypothesized planet located on the outer edges of our solar system that allegedly completes one orbit around the sun every 3,600 years and theorists believe that its gravitational influence has disrupted the orbits of other planets in the solar system over hundreds of years ago and that Earth’s time is nigh."
