Could this icy world is a sign of the ninth planet in the Solar system?

Our solar system has a new extreme object named L91. Not just the name that might make the forehead frowning, its orbit too. Yes, something very cool until its natural deserve to be called as the icy world is orbiting so far from the Sun so that one year in there is equivalent to 20 millennium on the Earth. So imagine. If you live there, the time span since the Pyramids of Giza were built until the Facebook was born, not even half a year.

L91 was located at a distance closer than 50 Astronomical Units (AU) or 50 times the distance of the Earth to the Sun. And its greatest distance reaches 1430 AU. "These places are right at a distance that can be detected," said astrophysicist Michelle Banniester of Queen's University Belfast who found it.

In her presentation at the meeting of the Division of Planetary Science, the American Astronomical Society on Monday, September 17, 2016, Bannister explained, L91 can be located so because Neptune and has an elliptical orbit.

At the birth, the objects that found by the Canada-France-Hawaii Telescope on Mauna Kea was located closer to the Sun. The difference between the closest and furthest distance to the Sun is not great.

According to Banniester, billions of years later the  L91 is kicked out by gravity of Neptune. Coupled with another star passing close to the solar system, then L91 farther away.. Well, the solar system which was originally calculated as a quiet world turned out to be dynamic and full of commotion. And L91 is one of the victims.

Not all believes with the hypothesis of Banniester. Off course, the solar system is dynamic but the oddities orbit of and distance does not have to be explained by Neptune or passing star.

"It's not a story that is not possible, but also are not needed," said Konstantin Batygin, an astronomer at the California Institute of Technology who was not involved invention, as quoted by Science on Monday.

According to him, the orbit change of L91 could be explained by the existence of a ninth planet in the solar system, which until now is still a hypothesis. Batygin and his partner, Mike Brown, is two people who at the beginning of 2016 have also write descriptions of a possible ninth planet in our big house.

According to Batygin, the ninth planet could give a good enough kick to make L91 away and its elongated orbit. Could it happen? *** [EKA | FROM VARIOUS SOURCES | MYSTERIOUS UNIVERSE]
