The sun has already lived about half its life and will not be closed in the next 4.5 billion years, says Vladimir Kuznetsov, director of the Earth Magnetism Institute of the Academy of Sciences of the Russian Academy of Sciences, director of the Ionosphere and Radio Broadcasting Extension.
According to Kuznetsov, the life span of the sun reaches about 10 billion years. The main star has already lived 4.5 billion years, so he has half of his life.
"The sun is at the forefront of the star's development (…) The time the star stays in it is the longest in its evolution, as it occupies 90% of its life," Kuznetsov said in an interview with Sputnik.
The scientist underlined that the thermoelectric reaction, which is the main source of solar energy, is constantly in the star's gut.
Kuznetsov believes that solar energy will change when all hydrogen in Saul will be burnt down and the destruction of helium and other heavier chemical elements begins. According to the expert, these processes will take about 5000 million years, and this will lead to the Sun, which will expand to Venus's orbit.

As a result, the star absorbs the next planet, burns the earth and starts to cool, becoming a white whale with only 10 kilometers radius and huge density. Planets like Mars, Jupiter and Saturn, orbit around this inert dwarf star.
