"Our solar system just got a little spookier," Chelsea Whyte wrote, after the International Astronomical Union's Minor Planet Center announced the discovery of a new dwarf planet on Oct.1.
The celestial ball of ice is being called The Goblin.
It was discovered orbiting the sun in the future. Pluto and its elongated path hints that the long sought Planet X can be traveled through the outer reaches of the solar system, as well.
The dwarf planet, officially called 2015 TG387, is about 300 kilometers in diameter.
It was first spotted by a team of astronomers using the Subaru telescope in Hawaii in October 2015, from its Halloween-theme name.
Its extremely elongated orbit means that it is 2,300 times as far from the sun as Earth is, and it never gets closer to the sun, than Pluto. The dwarf planet moves so slowly that it takes time to confirm its orbit with multiple observations.
"Currently, we would only detect TG387 when it is near their closest approach to the sun," David Tholen at the University of Hawaii said in a statement. "For some 99% of its 40,000-year orbit, it would be too faint to see."
He and his colleagues found The Goblin during their hunt for the hypothetical Planet X, a large planet believed to be lurking at the edge of the solar system that may account for disturbance in the orbits of smaller objects like The Goblin.
The gravity of such a large planet would be smaller than the size of the world.
The most distant objects in our solar system tend to have similar elongated orbits. The team ran simulations that included a super-earth-like planet in the distant solar system and found that such a planet would stabilize The Goblin's orbit.
These simulations do not prove that there is another massive planet in our solar system, but they are further evidence that something might be out there, "Chad Trujillo at North Arizona University said in a statement.
The more we learn about the universe we must continue to acknowledge its vastness is far beyond our brains' imaginations. Who can truly understand infinity?
