Mysterious Planet X could be captured by the Sun from another star system


    In the work “ Does Exoplanet in the Solar System ?”, Published on March 24 on, astronomers from the University of Lund (Sweden) and laboratories at the Bordeaux Observatory (France) numerically confirmed the possibility that the 9th planet, whose existence is indirectly confirmed some observations could be captured from the surrounding space by the gravity of the sun.

    Thus, this planet (if it exists) can be called an exoplanet — that is, a planet originating from another star system. Conducting computer simulation, scientists used three assumptions.

    - the captured planet was supposed to participate in the formation of such orbits of our own planets as we see today
    - the star, whose planet we stole, was supposed to have a planet with a large diameter orbit (more than 100 AU)
    - the capture of the planet was to take place from a distance of about 150 AU, so as not to bring turmoil into the Kuiper belt bodies.

    The capture of the planet could be accomplished at the time when the Sun was in the star cluster in which it was born. Some observations described in other papers suggest that it was born in a cluster of several thousand stars. After that, our star was gradually moving away from its place of birth.

    Computer simulations have confirmed that all three conditions are possible. For the first hundred million years in a cluster, stars really have planets with very eccentric orbits, while the planets themselves are of a size similar to Neptune. The “journey” of planets within a cluster from one star to another is also quite common.

    Although the existence of the 9th planet is still far from proven, it is already possible to argue about its origin. The great distance from the Sun and non-standard orbit of the planet can be fully explained by its alien origin.

    Earlier this year, astronomers received indirect evidence of the existence of the ninth planet in our solar system. According to their work, the movement of six objects of the Kuiper belt is best explained by the presence in the solar system of an hitherto unknown planet with a mass of 10 Earth masses in an elongated orbit. Its orbit at the same time should vary from 200 to 1200 AU. A few days ago, another Kuiper belt object successfully fitted into the overall picture of the existence of the ninth planet.
