Planet nine

Summary:
The scientists have discovered a new planet. It is about 10 times bigger than the Earth, and maybe it is the ninth planet in the Solar System. The scientists calculate that the orbite of this misterious planet is 20 times farther away from the Sun than the Earth, so this planet hasn't yet been observed directly. But they are finding the way to view it.

Personal opinion:
I hope that the scientists find this misterious planet, because it could be a very advanced discovery.
