It seems that planet Nine is not the only missing planet in our solar system. According to research, the elusive planet dubbed Planet Nine or Planet X may not be alone out there as researchers find evidence of more objects in the outer edges of our star system.
The group of scientists that came up with the idea that there is a giant planet lurking the outer edges of our star system has had their forum re-visited by researchers who have found that there are more planets still undiscovered lurking on the edge of our solar system.
Not long ago, researchers from the researchers from the California Institute of Technology (Caltech) found evidence of a ‘rogue’ planet, ten times the mass of Earth located somewhere on the edge of our solar system. According to initial calculations, the object takes around 20,000 years to complete a full orbit around our star.
