Two astronomers from Northern Arizona University in the United States that are engaged in the search for the ninth planet of the Solar system, discovered in the course of things the most remote from the sun the object of our planetary system. This is stated in the message on the website of the Carnegie institution.
A celestial object title 2014 FE72 is about 3000 times farther from the Sun than the Earth.

The tandem of scholars argues that yet undiscovered “planet X” must be on an orbit with a period of rotation around the Sun, about 15 thousand years and its mass is 10 times the mass of Earth.
