The researchers at Caltech have found new evidence of a giant planet with a highly elongated orbit in the outer solar system. The researchers have nicknamed it Planet Nine, which has a mass about 10 times that of earth and orbits 20 times farther from the sun. It would take this new planet 10,000 to 20,000 years to make one full orbit around the sun.
The planet was discovered using mathematical modeling and computer simulations but hasn’t been observed directly. The researchers Konstantin Batygin and Mike brown are confident this would be the real ninth planet.
This would be a real ninth planet,” says Brown, the Richard and Barbara Rosenberg Professor of Planetary Astronomy. “There have only been two true planets discovered since ancient times, and this would be a third. It’s a pretty substantial chunk of our solar system that’s still out there to be found, which is pretty exciting.
Brown adds that the ninth planet, which at 5,000 the mass of pluto, is large enough and there would be no debate whether it is a true planet. Not like past findings of dwarf planets.
