Planet X in the future may throw one or more gas giants, primarily Uranus and Neptune, outside the solar system. Research on this is directed to publication in the Monthly Notices of the Royal Astronomical Society, reported briefly by the University of Warwick.
The event predicted by the authors should occur in seven billion years, when the Sun turns into a red giant. By this time, Mercury will be absorbed by the star, and the conditions on Earth (if it is not destroyed by a star) will resemble those of Venus.
In this case, the mass of the Sun will decrease by half, as a result of which its gravitational influence on Jupiter, Saturn, Uranus and Neptune will decrease. These gas giants will gradually migrate towards the outskirts of the system, where Planet X is located.
The interaction of Planet X and the four giants will lead to the fact that at least one of the gas objects will be thrown out of the solar system. The more massive the outer celestial body, the stronger its influence on the inner planets.
Scientists reported on the possible detection of Planet X outside Pluto's orbit in mid-January 2016. The potential ninth planet of the system revolves around the Sun in an elongated orbit (and in a plane inclined relative to the Earth's orbit) with a period of 15 thousand years, and resembles Neptune in its physicochemical properties.
