NASA : Planet Nine Does Exist In Solar System: Social Trends
Planet Nine Does Exist The elusive ‘Planet Nine’ does exist, and may be 10 times the mass of the Earth and 20 times away from the Sun than Neptune, NASA scientists say.
Planet Nine could turn out to be our solar system’s missing ‘super Earth’ — a planet with a mass higher than the Earth’s, but substantially lower than the masses of ice giants Uranus and Neptune.
The signs so far are indirect, mainly its gravitational footprints, but that adds up to a compelling case, they have said.
Proofs That Its Exist :
“There are now five different lines of observational evidence pointing to the existence of Planet Nine,” said Konstantin Batygin, a planetary astrophysicist at the California Institute of Technology (Caltech) in the U.S.
“If you were to remove this explanation and imagine Planet Nine does not exist, then you generate more problems than you solve. All of a sudden, you have five different puzzles, and you must come up with five different theories to explain them,” said Mr. Batygin.
Six known objects in the distant Kuiper Belt, a region of icy bodies stretching from Neptune outward towards interstellar space, all have elliptical orbits pointing in the same direction, researchers have said.
However, these orbits also are tilted the same way, about 30 degrees “downward” compared to the pancake-like plane within which the planets orbit the Sun, they added.
“Over long periods of time, Planet Nine will make the entire solar-system plane precess or wobble, just like a top on a table, It turns out that Planet Nine provides a natural avenue for their generation. These things have been twisted out of the solar system plane with help from Planet Nine and then scattered inward by Neptune,” said Mr. Batygin.
“The possibility of a new planet is certainly an exciting one for me as a planetary scientist and for all of us,” said Jim Green, director of NASA’s Planetary Science Division.
“This is not, however, the detection or discovery of a new planet,” said Mr. Green.
“What we’re seeing is an early prediction based on modelling from limited observations. It’s the start of a process that could lead to an exciting result,” Mr.Green added.(Planet Nine Does Exist)
