When and how the sun will come out

The sun has lived about half of its life and will not die in the next 4.5 billion years, said Vladimir Kuznetsov, director of the Russian Institute of Earth, Ionosphere and Expansion of the Radio Wave of the Russian Academy of Sciences.

According to Kuznetsov, the life expectancy of the Sun reaches around 10 billion years. The main star has lived 4.5 billion years, so he has about half his life left.

"The sun is in the main sequence of star evolution (…) The time at which stars remain in it is the most lasting in its evolution, because it occupies 90% of its life," Kuznetsov said in an interview with Sputnik.

Scientists stress that thermonuclear reactions – which are the main source of solar energy – occur continuously in the star's stomach.

Kuznetsov believes that solar energy will change when all the hydrogen in the Sun burns and when the destruction of helium and other heavier chemical elements begins. According to experts, these processes will last around 5,000 million years and will cause the Sun to expand into Venus's orbit.

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