Detecting Goblin dwarf planet redefines the Solar System

The discovery of Goblin dwarf plan changes what is known about the edge of the Solar System and shows signs of the existence of the mysterious 9th Planet.

Guardian on October 2 reported that astronomers discovered Goblin dwarf planet while searching for the 9th planet according to the theory that there is a large planet that exists on the outer edge of the Solar System, the The area is called Oort Cloud Nebula .

Observers have not directly seen. However, the Goblin dwarf planet seems to be influenced by the gravity of the unidentified giant. This makes astronomers even more certain about the existence of the 9th Planet.

Goblin is an icy planet with an estimated diameter of 300 km. It lies on elongated elliptical orbit. At the closest position, its distance to the Sun is 2.5 times greater than the distance from Pluto to the Sun.

The goblin mainly moves at the far edge of the solar system, with a distance of 60 times the distance from the sun. This means that the Goblin needs 40,000 years to complete a cycle around the Sun.

This is the third dwarf planet found on the edge of the Solar System. Previously, scientists discovered two objects named Sedna and 2012 VP113. The Oort Cloud Area if it was previously thought to be cold, dark and empty, it now seems to contain a large number of strange celestial bodies.

"We have only recently discovered what the region around the Solar System looks like and can contain anything ," said Scott Sheppard, a member of the Carnegie Institute of Science in Washington DC.

'We believe that there are thousands of dwarf planets around the solar system. We're just seeing the tip of the iceberg , ' Sheppard said.

Interestingly, the orbits of the three bodies have been found to be clustered, ie they may be under the influence of another unidentified giant. Scientists believe this is a sign that the 9th planet is 10 times more massive than the Earth.

Konstantin Batygin, assistant professor in planetary science at Caltech, calls these new observations 'indeed a great discovery'. He had many years of studying the 9th Planetary hypothesis.

'Although it has been through many centuries of research, our understanding of the Solar System is still incomplete. This discovery contributes to increasingly rich records of celestial bodies, showing the impact of the 9th planet '.

The official name of the new dwarf planet was found to be 2015 TG387 , according to the Dwarf Planet Center International Astronomical Association. However, it has a more memorable nickname than a Goblin because research was conducted around the time near Halloween, said University of Hawaii scientist David Tholen. Mr. Tholen is one of the members of the observation project.

In this study, scientists used the Subaru telescope 8m long of Japan. The device placed on the top has stopped working in Hawaii. The Subaru telescope is the only instrument in the world that can produce images that help explore the Solar System's edge, and have a large enough observation field to detect rare objects in the sky.

'For other large glasses, observations are similar to looking through a straw. Therefore, they are only relevant when observing objects that you already know the location of, not to find new objects , 'Sheppard said.

In November, the research team will begin a new observation in the hope of finding more celestial bodies, including the mysterious 9th Planet.
