What is the planet x?

Planet X (pronounced as a letter, not a Roman numeral) is a hypothetical planet that many astronomers have been looking for over the years. When searching for the planet X, astronomers "found" Pluto and Xena or Eris, now all classified dwarf planets and did not consider themselves real planets. Planet X was not usually considered 10. The planet, because when it started searching, experts on astronomy discovered only eight. Instead, the name only means an unknown planet that exists behind Neptunem. Some of the mathematical irregularities in the orbit of this planet and Neptune indicate the presence of another planet behind Neptunem. When Pluto was discovered in 1930, he was not big enough to explain the orbital patterns of all four planets; So Science was looking for something outside Pluto, maybe a gas giant as big as Jupiter.

For most of the 20th century, astronomers continue to postpone the existence of the planet X and tried it velto find me hard. In the 1890s of the 20th century, one of the arguments against the existence of such a planet was that the probes sent to space did not move in a way that would suggest a strong gravitational thrust of the planet X. Another contributor to the demise of Planet X is that the space probe Voyager 2 provided more accurately measurement of Neptune.

There are some scientists who still represent the possible existence of the planet X, but reimaginated the concept of what the planet can be. Some suggest a brown dwarf star and not a planet. Other astronomers, such as Patryk Lykawka, made calculations that indicate that we will definitely determine 2013, whether such a planet exists.

The

hypothetical other planet has captured the imagination of many and appears in many SCI -Fi films, TV shows and books. Robert Heinlein's novel The Puppet Masters suggests ten planets in the solar system, the last called Kalki. Animated characters like Duck Dodgers and some of theTransformers refer to Planet X. The fictitious rendering of the planet can refer to the 10th planet or the hypothetized huge planet that not yet, and never has to find because it does not exist.
