Planet Nine's gravitational field slowly influenced the orbits over the 4.5 billion years since the solar system formed, Bailey says. "All of a sudden, you have five different puzzles, and you must come up with five different theories to explain them", said Batygin.
NASA experts thus underscore the fact that the existence of the ninth planet is not fully proven, but a heavenly body does not threaten the well-being of the Earth.
Batygin in 2016 published a study examining the six known objects in the Kuiper Belt, a circumstellar disc in the Solar System beyond the planets that extends from the orbit of Neptune towards interstellar space.
The science communities since a long time have been debating upon the existence of Planet Nine.
His findings revealed that the objects all had elliptical orbits that point in the same direction and are tilted 30 degrees "downward" compared to the plane in which the eight planets circle the sun.
The researchers believe that the detection of the Ninth Planet is the key to details about its origin. These serve as evidence to the planet's existence.
A picture published by Futurism.com shows the supposed orbit of the six most distant Kuiper Belt objects and Planet Nine, demonstrating how the latter explains the former.
"No other model can explain the weirdness of these high- inclination orbits", Batygin said.
Batygin said that the ninth planet would make the entire plane of our solar system unstable in future. They also had 30-degrees tilt in their orbitals while the now known eight solar planets travelled in the same plane around the sun. According to the press release, Batygin and Brown are now using the Subaru Telescope at Mauna Kea Observatory in Hawaii to try to do just that. NASA said that human eyes might find things that automated computer algorithms miss.
