January last year - a statement from astronomers that celestial bodies move along very unusual trajectories in the Kuiper belt, which is one of the border parts of our solar system. In this regard, it is likely that there is a fairly large and unknown object - the mysterious ninth planet. True, it is very difficult to consider it so far, since, according to scientists, no coincidence in the light occurs. However, after a few years, the hypothetical celestial body will definitely be noticeable.
Supposedly, it weighs twenty times more than the Earth, and the distance to the Sun is about three hundred and fifty astronomical units. True, according to modern models of planetary formation, it is not particularly clear how such a massive object could form so far from the "mother" star. Among other things, the orbit of this celestial body strongly deviates from the planes familiar to our system by sixty degrees. In connection with such and other factors, many astronomers began to assume that in front of them is an exoplanet, which originally formed not at all near the Sun, but simply later captured it by a star. Nevertheless, in a new work presented by British and Swiss scientists, this hypothesis is completely and completely refuted. Richard Parker, head of the group, explains in the text,that our star is located as if in not the currently "populated" part of the Milky Way.
True, when the Sun was just formed and began to collect planets, there were other stars around in large numbers. It seems like this is why, if we follow that early hypothesis, some newborn planet could be captured. Richard Parker and his team decided to test this through computer simulations. It turned out that it is not particularly dependent on how the star can capture some planet, on the number of stars themselves nearby. That is, one cannot support the hypothesis of the possibility of a certain celestial body X passing later into our system by the fact that young "suns" were located nearby.
The star could not catch an alien object with a distant and unstable orbit. However, there was an influence of the internal movement of a group of luminaries - in particular, when it expanded, such events happened more often. In fact, stars can rarely "exchange" planets. Maximum six percent, not more. Thus, the researchers concluded that it is unlikely that the Sun took the planet away from another star like this. Such a scenario is not one hundred percent, but still relatively unlikely. Accordingly, this option is definitely swept aside.
However, there is an opinion that planet X is still not from our solar system - if it was brought from somewhere else. Such a "gift" is really possible - in the case of a very powerful supernova explosion of another star. That is, there is a large star with planets around it. Suddenly the inner layer of the star burns out, and the outer one remains heavy, and since there is nothing more to hold it, it “falls through” in a peculiar way - then the object begins to splash out, so to speak, “turning inside out”. This is how the star turns into a supernova and explodes. At the same time, some of the nearby planets immediately burn up, and some are thrown away with a large amount of energy, rolling through space like a kind of cosmic shock wave. Some, however, still then remain with the remnants of the star. The same ones that threw awaythey can no longer return to it - they are too far away, and the star does not have enough gravity to pick them up again.
Then the planet simply "falls" in space until it is attracted by another object. Hypothetically, the Sun could have done so in due time. However, it is interesting in this case when this could have happened and whether it affected the planets of our star system in the future. Still, if a large object reaches the collection of other celestial bodies, it is not a fact that this would not have been without some consequences. However, all this requires proof.

There is, however, a third version - the planet nevertheless formed right in our system, however, it may have begun to do so later than others. And for all its massiveness, it could not pass a kind of "barrier" of gas giants. In particular, Jupiter could especially interfere, which, according to the researchers, did not allow any rocky planet to form larger than those that exist.
Moreover, this gas giant was formed the very first. At one time, Jupiter destroyed the planet located between him and Mars. Theoretically, such a threat could have been for the celestial body X, but it was somehow simply "squeezed" into the Kuiper belt. Alternatively, in those distant years it was slightly less than it is now assumed, however, planetary formation continued - and the object was "replenished" with some other "embryos" that took place in this part of the solar system. However, this version is also very conditional and can be criticized, since there are different interpretations of different phenomena. Not everything is known about the solar system and the laws of interaction of objects in it.
It is curious that although there is very little information about planet X, some experts have almost begun to make plans for its colonization. According to experts, although the object is very far away, it is clearly cold due to such a distance, and so on, hypothetically, a person may well explore it. Especially if the planet is an "alien" - initially, in its system, it could have been located not on the border itself - accordingly, even if it froze, something useful was theoretically preserved.
