Astronomers managed to find a small object far beyond Pluto, which revolves around the Sun in a lonely oblong loop. This discovery supports the idea of the existence of a more distant and larger Planet X, wandering on the edge of the Solar System.
Most likely, the 2015 TG387 is a dwarf planet with a diameter of 300 km, due to which it resembles Massachusetts in size. She was found at a distance of 80 a. e. From the Sun (1 a. e. is the Earth-Moon distance or 150 million km). It turns out that the 2015 TG387 is 2.5 times farther from the star than Pluto.

A new find was also called the “Goblin” and presented to the members of the International Astronomical Union on October 2. An astronomer from the Carnegie Institute observed similarities in the orbits of distant objects, such as the 2015 TG387, which led to the idea of the existence of an undiscovered and mysterious distant world, several times larger than the Earth. This Planet X hypothetically lives beyond the orbit of Pluto in the hundreds of a. e. Scientists believe that the more we are able to find intermediate objects, the faster we get to the riddle. 2015 TG387 revolves around a star with a periodicity of 40,000 years and settling on 2300 a. e. at the most distant point. In fact, to see this object is a great luck.
It is also interesting that Planet X is able to influence the 2015 TG387 as well as other extremely distant objects of the system. Simulations do not prove the existence of another large planet, but they hint at the presence of something huge.
