Orbiting the Sun from beyond Pluto, a new dwarf planet nicknamed the Goblin was discovered by the scientists from the Carnegie Institution for Science, the University of Northern Arizona and the University of Hawaii, as part of an ongoing search for dwarf planets and Planet X.
The Goblin dwarf planet, also known as 2015 TG387, is a body of about 300 kilometers in diameter that orbits the Sun in 40,000 years. It was observed for the first time in 2015 in the Inner Oort Cloud where other similar objects exist.
“These so-called Inner Oort Cloud objects like 2015 TG387, 2012 VP113, and Sedna are isolated from most of the Solar System’s known mass, which makes them immensely interesting. They can be used as probes to understand what is happening at the edge of our Solar System,” explained Scott Sheppard from the Carnegie Institution for Science.
According to the scientists, there might be more dwarf planets in the Inner Oort Cloud.
Every discovery of a dwarf planet like the Goblin (2015 TG387) brings astronomers one step closer to finding Planet X
The fascinating thing about this discovery is that TG387 is one of a dozen other space rocks beyond the Kuiper Belt that boast similar orbits, converging at points of maximum proximity to the Sun.
“These distant objects are like breadcrumbs leading us to Planet X. The more of them we can find, the better we can understand the outer Solar System and the possible planet that we think is shaping their orbits, a discovery that would redefine our knowledge of the Solar System’s evolution,” said Sheppard.
“What makes this result really interesting is that Planet X seems to affect 2015 TG387 the same way as all the other extremely distant Solar System objects. 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” added Trujillo.
