PLANET II

However, after a huge amount of studies, he and his partner found that the theory of Planet Nine is the only one that explains the phenomenon.
"Murderer of Pluto"
So far Brown was known as one of the men responsible for that Pluto no longer considered a planet.
His discovery of more than 30 dwarf planets Eris among them, a bigger star than Pluto led the International Astronomical Union (IAU in English) reclassify its definition of what constitutes a planet and Pluto relegated to the category of dwarf planet.
Brown Wednesday which tweets under the nicknameplutokiller (Pluto murderer) - told reporters he hoped his new announcement reproach him who claimed to have left the solar system with only eight planets.
That includes his own daughter.
"She still mad at me for half Pluto's relegation, although he had just been born when it happened," he told The Washington Post.
"A few years ago suggested that forgive me if I find a new planet, so I guess I've worked on this for her," he said.
Credibility
But can it really be said that a new planet was found?
How reliable is the announcement?
BBC asked him the director of the Planetary Science Division of the National Administration of Aeronautics and Space of the United States, better known as NASA.
In an exclusive interview, Jim Green told this newspaper that both Brown and Batygin are highly qualified scientists, leaders in their field.
He stressed the importance of their research.
"This is a huge step forward to understand what happens in a region of our solar system that we know virtually nothing," said the objects found beyond Pluto in question.
"It's a really important point," he added.
However, NASA managers said that will require many more observations to confirm the theory of these experts, since the presence of a ninth planet "can not be the only explanation for what they saw."
Processes
Adriana Ocampo, head of the New Horizons (New Frontiers) NASA program in 2015 revealed previously unseen images of Pluto, he told the BBC that it is common planetary discoveries begin with predictions.

"The existence of both Neptune and Pluto was predicted long before they were first seen," he said.
However, the expert noted that the announcement of a ninth planet is only a "possibility" and that it becomes a fact, the existence of the star must be supported by at least half a dozen space observatories.
In that sense, Ocampo noted that the importance of work released this Wednesday is that more scientists will be in search of this alleged Planet Nine, which will increase the chances that one be found, if it exists.

Brown himself said he published his work with that hope.
"If other people astrónomos- -best get excited about the idea of ​​finding Planet Nine maybe we can see it in a couple of years," esperanzó.
