Recent findings have hinted towards the existence of planets situated beyond our solar system aa the race to identify the planet has begun.
It all started with the discovery of a small icy world far away from Pluto. It is presumed that a vast number of such worlds exist beyond the Oort cloud.
It is thought that a massive planet may exist at the edge of the solar system.
The small world, nicknamed Goblin, is situated at approximately 80 astronomical units from the Sun. For reference, Pluto is situated at approximately 34 astronomical units. What makes the discovery noteworthy is the fact that the icy world has a particularly bizarre orbit, as it appears to be overly elongated.
The world is about 300 miles wide and the orbit takes quite a time to complete at an estimated 40.000 years. This means that the world never gets close to the sun, as its perihelion or closest point to the sun is the third farthest after Pluto.
Only two other objects, 2012 VP113 and Sedna are farther than Goblin. The fact that they have a similar path throughout their orbit may hint towards a common influence among them. Since objects like this are isolated from the known mass of the solar system which means that the force comes from an external planet.
Astronomers agree that hundreds of planets like Goblin can exist out there, but they are very hard to identify and track. Even Goblin can only be spotted when it is close enough to the sun. The discovery marks a landmark in deep space exploration as it proves that planet may in fact form without the influence of a solar system.
Some believe that a super planet may influence the trajectories of the icy worlds but its existence remains a mystery for now as there is no certain way to prove its existence.
It remains to bee seen what the astronomers will find in the future.
