A New Ninth Planet Might Have Been Detected, Scientists Say
Unhappy that Pluto is not a planet anymore? Don’t be concerned, Caltech researchers might have found a brand new planet lurking within the outer reaches of our photo voltaic system.
They’re calling it "Planet 9" for now. The planet, if it exists, has a mass 10 occasions that of Earth and takes between 10,000 and 20,000 years to orbit the solar.
Planet 9 has not truly been noticed. As an alternative, proof of the planet was found via mathematical modeling and pc simulations.
"Though we have been initially fairly skeptical that this planet might exist, as we continued to research its orbit and what it might imply for the outer photo voltaic system, we grow to be more and more satisfied that it’s on the market," Konstantin Batygin, an assistant professor of planetary science at Caltech, stated in a press release.
The analysis from Batygin and Mike Brown, whose discoveries led to the downgrading of Pluto to a "dwarf planet," was revealed Wednesday in The Astronomical Journal.
It began in 2014 with the investigation of thirteen objects within the Kuiper Belt — a area of the photo voltaic system past Neptune full of comets and different icy our bodies, in addition to dwarf planets together with Pluto.
Six of these objects had an orbit that steered they have been circling some distant object, which the researchers now consider is the ninth planet in our photo voltaic system. Though they consider they know the planet’s orbit, they hope to truly find it utilizing a big telescope.
"This might be an actual ninth planet," Brown stated. "There have solely been two true planets found since historic occasions, and this may be a 3rd. It is a fairly substantial chunk of our photo voltaic system that is nonetheless on the market to be discovered, which is fairly thrilling."
