The discovery of the new planet may now trigger conspiracy theorists to claim that it could be the Nibiru, a rogue planet lurking outside our solar system to enter any time to cause destruction. It takes this planetoid 40,000 years to loop around the Sun once and it's one of the most inhospitable places ever discovered by humans.
Sheppard said he predicts thousands of objects the same size as 2015 TG387 dot the rim of our solar system. "Currently we would only detect 2015 TG387 when it is near its closest approach to the Sun". Planet X on the other hand, which is postulated to be 60 billion miles from the Sun, is expected to take 20,000 years to complete one orbit around the Sun! It's one of a group of objects that are also called Inner Oort Cloud Objects (IOCOs).
The first observation of the object was made in October 2015, at the Subaru eight-meter telescope atop Mauna Kea in Hawaii.
For context, Pluto is about 34 AU. The first thing that came to their minds was the mysterious Planet X. Scientists believe that like other objects at the edge of the solar system, the Goblin is pushed into similar objects by an invisible force, which they suggest could be Planet X. Using the basic parameters they have for Planet X, they concluded that the Goblin behaves like it's "shepherded" by a planet but doesn't come close to that planet.
In the recent development, it has been seen that an unknown dwarf planet is circling the far reaches of the solar system.

Democrats also objected to a statement by committee Chair Chuck Grassley, R-Iowa, who said the investigation "found no hint of misconduct".

It was argued that the loud noise of traditional clapping and whooping pose an issue to students with anxiety or sensory issues. Student leaders at the university declared that Kipling stood "for the opposite of liberation, empowerment, and human rights".

But worldwide efforts to help are gearing up after the government overcame a traditional reluctance to take foreign aid. Homes were sucked into the earth, torn apart and shunted hundreds of meters by the churning mud.
An artist's conception of distant Planet X, which could be shaping the orbits of smaller extremely distant objects.
Scott Sheppard, from the Carnegie Institution for Science, said of the Goblin, "Every small object we find that is isolated like this will bring us closer to finding the planet". Scott Sheppard, of the Carnegie Institution for Science, explains that "most of it is found, and the more we understand the frontier of the solar system and the influence of a possible planet that, we think, shapes their orbit".
Only a few known objects in our solar system have comparable orbits, such as dwarf planets 2012 VP113 (nickname: Biden) and Sedna. "These simulations do not prove that there's another massive planet in our Solar System, but they are further evidence that something big could be out there", Trujillo said in a statement. Batygin, in a 2016 paper in the Astronomical Journal, estimated Planet Nine would be up to 10 times as massive as Earth.
Theorbit flattened the Goblin could therefore be the outcome of the influence of planet X.
So if the Goblin is unaffected by the gas giant planets in our solar system, what contributes to its unusual orbit? Objects close to the sun move rapidly, objects farther away more slowly. "We are only seeing the tip of the ice berg", Sheppard said in an email.
Meanwhile, Sheppard and the rest of his research team will begin a new search starting next month to locate other objects in the fringes of the solar system, including Planet Nine.
