Hey
Charlie ! Could a new planet exist in our solar system ?
In January 2015, Caltech astronomers Konstantin Batygin and Mike Brown
have found mathematical evidence and computer simulations suggesting
there may be a ninth planet in the solar system right behind Neptune.
They have called it « planet nine ». Since « planet nine» so far
has not yet been observed directly, its existence stays only
theoretical at this point. From 2006 on, school all over the world
has taught that the solar system contained 8 planets. But it may have
been 9 planets all along.
The
hypothetical planet is believed to have 10 times the mass of Earth
and about 4 times Earth's diameter. Moreover, Planet nine is
estimated to have a very long orbit that take between 10,000 to
20,000 years to orbit the sun.
Evidence
continues to mount for its existence through its gravitional effects.
There are three separate reasons that proves its existence.The
existence of a large object could explain the unique orbits of at
least five smaller objects discovered in the distant Kuiper Belt. The
Kuiper Belt is a vast region of primordial debris in the outer Solar
System, extending from the orbit of Neptune. All five objects have
elliptical orbits that go in the same direction. Normally, the orbits
should be all over the place. The second point shows that Planet
Nine's influence might have tilted the entire solar system except the
sun. These two reasons on their own proves that all of this is
influence by a large gravitational source. The third explanation
comes from the computer simulations predecting that more objects in
the solar system should be titled out of the plane.
This
is not the first time that a planet in our system solar is discovered
theoritically. Deviations in the orbit of Uranus has been observed.
Neptune was pridicted to exist before it was actually discovered
using similiar mathematical modeles back in 1846.
