When and how the Sun will turn off


The Sun has already lived about half of his life and will not go out in the next 4.500 million years, says Vladímir Kuznetsov, director of the Institute of Terrestrial Magnetism, Ionosphere and Expansion of the # 39; Waves of Radio of the Russian Academy of Sciences.

According to Kuznetsov, the Sun's life expectancy reaches about 10,000 million years. The main star has already had 4,500 million years, so it has approximately half of its life.

"The Sun is in the main sequence of the evolution of stars (…) The time during which the star remains in it is the most lasting in its evolution, as it occupies 90% of his life, "Kuznetsov said in an interview with Sputnik.

The scientist emphasized that a thermonuclear reaction – which is the main source of solar energy – constantly passes in the bowels of the star.

Kuznetsov believes that solar energy will change when all hydrogen in the Sun is burning and when helium destruction and heavier chemical elements begin. According to the expert, these processes will occur in approximately 5,000 million years and will lead to the sun being extended to the Venus orbit.

As a result, the star will absorb the nearest planets, burn the Earth and begin to cool, becoming a dwarf white with a radius of only 10 kilometers and a colossal density. Planets like Mars, Jupiter, and Saturn orbit around this star drone inert.
