There is no "Planet X". See links.
"Planet X" is the temporary name given to a planet that lacks a designation. Pluto was, at one point, known as Planet X. Some members of the cults that have formed around the Nibiru Cataclysm Theory believe, in ignorance, that 'Planet X' is NASA's secret name for Nibiru, a mythical, large, planet-like object that is predicted (by Nancy Lieder) to collide with Earth.
Yes and no. "Planet X" is a designation given temporarily to any new planet with no name. It does not refer to a specific planet, and once a planet is given a name, 'Planet X' is discarded as a title. Several planets, including Pluto, have been referred to as "Planet X."Supporters of the Nibiru Cataclysm Theory sometimes claim that "Planet X" is NASA's method of keeping "Nibiru," a mythical, large planet-like object, secret, as part of a cover up. There is no scientific foundation for this "theory."
Planet X is a hypothetical planet that has not been observed or confirmed by astronomers. It is thought to be a large, distant planet in our solar system, but its appearance is unknown until it is officially discovered and studied.
Planet X was a hypothetical planet which was searched for after the discovery of planet Neptune. `Planet-X` does not exist.
No, Planet X does not exist.
For many years an unknown planet was thought to exist, that caused discrepancies in the orbits of Neptune and Uranus. This was dubbed Planet X. With improved measurements from the Voyager space probes, this Planet X was disproved, most astronomers believe now that it does not exist - that there are no more large undiscovered planets beyond Neptune that are in orbit around our sun. Several minor planets have been discovered further out though.
No
Planet x is the planet behind Pluto which is commonly reffered to as Selena but is not yet a planet(or clarified planet).
The name of planet X is Nibiru
Nowhere. There is currently no planet called planet X. It is a lie
Planet X does exist but there are about 3 Dwarf planets that have simularities to Plznet X. Planet X has not yet been discovered.
Planet X was nothing because it does not exist and never did.
