The 9th planet can cause disaster for the solar system

Research by British scientists shows that if it really exists, the 9th planet could cause a terrible chaos for the Solar System once the Sun dies.

In a study published recently, Dr. Dimitri Veras of the Department of Physics, University of Warwick, England, said that if the 9th planet, the hypothetical planet is located on the outer rim of the solar system, exists, it has can cause the Solar System disaster when the Sun dies , according to Science Daily.

According to the scenario previously built by astronomers, when the Sun begins to die in about 7 billion years, its mass will be halved and the Sun will swell, swallowing the Earth before it cools, Become a white dwarf. This process will push Jupiter, Saturn, Uranus, Neptune to a safe location far away.

However, Dr. Veras realized the existence of the 9th planet could change the scenario. He discovered that the planet could not be pushed away like other planets that moved chaotic along with the four giant planets of the solar system, most notably Uranus and Neptune. . As a result, they risk colliding with the 9th planet and being knocked out of the solar system permanently.

Using a special model to simulate the death of the planetary system, Dr. Veras mapped various positions at which the 9th planet was able to change the future of the solar system. The larger the planet has, the more distant it is, the higher its risk of hitting planets in the solar system.

Dr. Veras's findings help increase understanding of planetary structures in different solar systems. Nearly half of the existing white dwarfs contain rocks, most likely a sign of debris from similar process to another planetary system.

"The existence of a large distant planet can fundamentally alter the fate of the solar system. Uranus and Neptune may no longer be safe from the Sun's death. The solar system will depend on the masses and orbital properties of the ninth planet if it exists , ' explains Dr. Veras.
