Planet 9 Update: Exoplanet A Strong Theory

Planet 9 is not part of the original members of the solar system. According to the new research by the astronomers at the Lund University in Swede, the mysterious ninth planet is an exoplanet.

The intriguing Planet may have been "pushed" by other planets, that when it ended up in the orbit too wide around its own star, the sun might have taken the chance to steal and get Planet 9 from the original star. Researcher Alexander Mustill further explained that when the sun eventually retreated from the stellar cluster wherein it was born, the ninth planet remained in an orbit around the sun.

Most of the stars were born in clusters. The newborn stars' orbits often place them in a considerably close proximity. Based on the new simulation, our sun and another star passed by one another and our sun's gravitational pull was able to pull in an exoplanet, an incident which has gone unnoticed until recently, Daily Galaxy reported.

Astronomers believe that there is a possibility that before the stealing, Planets 9, which is otherwise known as Planet X, was pushed to the outside edges of its original star system by the other planet. Evidence was also presented by the researchers in The Astrophysical Journal earlier this year indicating the presence of the ninth planet. Based on the report, the astronomers were able to interpret its existence by examining the orbits of numerous icy objects past Neptune. They noticed that the orbits of these Kuiper belt objects, or KBOs, have the same anomalies.

The orbital strangeness implied that the objects were all being affected by one source, the gravity of a big object, Planet 9. While there is still no Planet 9 image, nor a point of light, and there is still no idea if it is built of ice, gas or rock, the researchers said that all they know is that its mass is possibly ten times the Earth's mass, according to UPI.

Planet 9 theory will just be a theory, as more research is needed to validate the true origin of the planet.
