Astronomers from Spain and the UK accused the destruction of Planet X in the solar system. This means that some large celestial bodies as a result of its gravitational influence will leave the planetary system.
Scientists, using the known constraints on the Planet X, conducted computer simulations within the N-body problem.
Scientists interested in the impact of a celestial object on the movement of six extreme trans-Neptunium objects – celestial bodies beyond the orbit of Neptune, semi-major axis of more than 150 astronomical units, and perihelion – 30 astronomical units.
The simulation showed that the orbit of the dwarf planet Sedna and 2012 VP113 candidate will remain stable over the next few hundred million years. On the other hand, the trajectory of trans-Neptunium objects 2004 VN112, TG422 2007 and 2013 RF98 (in diameter, these celestial bodies reach 100-300 km) are unstable over time and after a few tens of millions of years, they can be thrown away by Planet X out of the solar system.
About the possible discovery of Planet X beyond the orbit of Pluto, scientists reported in mid-January. Potential ninth planet in the system revolves around the Sun in an elongated orbit (and inclined relative to the plane of Earth’s orbit) with a period of 15,000 years.
Based on available data about Planet X later, other astronomers have come to the following conclusions. The radius of the celestial body is 3.7 times larger than that of the Earth. Its temperature atmosphere consisting of helium and hydrogen is equal to minus 226 degrees Celsius. Under the gas shell at a temperature of minus 63 degrees Celsius is a layer of water ice.
