The star of the sun is a red-hot, bright ball of plasma that dominates the sky in the daytime, being the largest object in the solar system. The sun is a star that provides the Earth with warmth and light, and, as we will see, this is not an ordinary star.
The star sun is in an ideal environment
The sun is a single star, whereas most stars exist in multiple systems. The planet in such a system will suffer from extreme temperature fluctuations. The position of the Sun star in our spiral Milky Way galaxy is ideal. Its orbit is fairly round, which means that our star will not fit too close to the inner part of the galaxy, for which supernovae are more typical, unusually strong flares of stars. The unique star The sun rotates in an orbit almost parallel to the galactic plane - otherwise, the intersection of this plane would be devastating.
What sun, how does it shine?
In 1939 Hans Bethe put forward the hypothesis that the Sun and other stars are energized by nuclear fusion - this theory brought him the Nobel Prize in 1967 in the field of physics. In the process of synthesis, very rapidly moving hydrogen nuclei are combined to turn into helium - this requires a temperature of millions of degrees. Some mass is lost and converted into a huge amount of energy, according to Einstein's famous formula E = mc2.6 Thus, the Sun is a semblance of a giant hydrogen bomb.
