Those of us who grew up in the 1990s and early millenniums learned that the Solar System has nine planets. That’s what they told us at school. However, since 2006 different scientific groups determined that Pluto did not meet the conditions and characteristics to qualify as “world”.
Since then, the star system we orbit has reduced its number of worlds to eight. That ninth planet, which is not Pluto, appears to be hovering in a mysterious region within our neighborhood of the Milky Way.
This particular world is a different one from the so-called ‘Planet Nine’ or ‘Planet X’ that is theorized to be in the vicinity of Neptune.. That world has not yet been confirmed by experts in astronomy or astrophysics.
The one we are talking about in this review is an exoplanet that would have arrived from the exteriors of our system, dragged by the gravitational center of the Sun. However, it did not manage to enter completely until it became visible from our surface, instead it would have stayed in a area called the Oort cloud.
This region of the Solar System is located after the Kuiper Belt (asteroid belt) and would also gather an endless number of small objects such as rocks that orbit the Sun. Among these could be this great world that is still elusive to terrestrial observatories.
The theory reviewed by the website Futurism says: “Dynamic instabilities between giant planets are believed to be nearly ubiquitous, culminating in the ejection of one or more planets into interstellar space. We found that a fraction of the planets that would otherwise have been ejected are stuck in very wide orbits, analogous to those of Oort cloud comets.”
