Astronomers
are now quite certain about the presence of a ninth planet in the solar system.
Konstantin Batygin and Mike Brown, two CalTech researchers, suggest the new
planet is nearly 10 times the mass of Earth and also has an atmosphere of
hydrogen and helium. According to the Science magazine, the mysterious
"Planet X" moves in quite a distant orbit beyond Neptune. The
scientists haven't directly observed Planet X itself, but the evidence indicates
it exists because of the exceptional formation of six objects when they come
closest to the sun, according to Science.
According to
the researchers there's a 0.007 percent probability that the strange formation
is due to chance, and instead are pretty assured it's a ninth planet. They
believe they will witness the planet directly with a telescope in next five
years, according to The Associated Press. So the question is, where did this
possible planet originated from? Astronomers have previously proposed that there
might be a missing planet in our solar system, with some speculation that a
collision triggered it to be ejected out of our system some almost 4 billion
years ago. And astronomers suggest that collision may have been with Jupiter.
Lead researcher Batygin said in a statement :
"Although we were initially quite skeptical that this planet could exist, as we continued to investigate its orbit and what it would mean for the outer solar system, we become increasingly convinced that it is out there. There is solid evidence that the solar system's planetary census is incomplete."
Batygin and
Brown explained their results in The Astronomical Journal on Wednesday.
The finding
is also the second time that Brown has rewritten the way we think about our
solar system. In 2005, he made a key discovery that directed researchers to
reclassify Pluto as a dwarf planet. In a statement on Wednesday, Brown -- whose
Twitter handle is @plutokiller -- suggested to the role he played in getting
Pluto reclassified, mentioning that the new finding was 5,000 times the mass of
Pluto and was certainly a planet.
He said, "All those people who are mad that Pluto is no longer a planet can be thrilled to know that there is a real planet out there still to be found,"
