Planet Nine discovered as suspected 9th planet in solar system

Planet Nine discovered as suspected 9th planet in solar system. January. 22, 2016 08:11. by 이설 기자snow@donga.com. Is there a plant that will replace "Pluto" that was exited from our solar system?

Some scientists claim that there exists "Planet Nine" beyond Pluto. According to the U.S. weekly New Yorker, a research team led by Prof. Mike Brown at California Institute of Technology has published Wednesday their study suggesting that they found evidence that giant Ninth Planet exists outside Pluto in "Astronomy Journal," one of the four major astronomy journals in the world.

According to the study, Planet Nine has a mass about five to 10 times the size of the earth, and is the fifth largest after Jupiter, Saturn, Uranus, and Neptune. An oval-shaped orbit, the planet has is estimated to be located at about 32 billion kilometers from the sun when it is closest from the earth, and about 160 billion kilometers, when it is the most remote. The researchers estimated that it would take the planet between 10,000 and 20,000 years to make just one full orbit.”

Prof. Brown said, “We did not see ‘Planet Nine’ in person with a microscope, but the mass of this planet will amount to at least 5,000 times that of Pluto. The research team monitored the scene of six small planets rotating through an oval orbit at the same angle with a microscope. The probability of multiple stars to rotate at the same angle is less than one 14,000th, and the researchers said this is evidence that there are planets that have gravity affecting them.”

“Identifying the existence of a planet beyond Pluto was one of the major research topics over the past 10 years,” the New Yorker said. “Scientists worldwide have high expectation on the credibility of Prof. Brown’s study.” However, certain scientists, including planet science bureau at NASA, were more cautious, saying, “We have wait and see further.”
