What temperature does the sun have?

The Sun is the largest object in our Solar System and contains approximately 98% of its total mass. It would take one hundred nine Earth to complete the solar disk, and its interior could contain more than 1.3 million Earths.

In the nineteenth century, it was already possible to reduce the temperature of the surface of the Sun from its brightness and its distribution with respect to the wavelength of the visible spectrum.

 The visible outer layer of the Sun is called the photosphere and has a temperature of 6,000 ° C (11,000 ° F) and this is why the Sun is yellow; if its surface were hotter it would look bluer and if it were cooler it would look redder. This layer has a stained appearance due to the turbulent eruptions of energy on the surface and do you know which country has first sunrise in the world.

The solar energy is created in the interior of the sun. It is here that the temperature ( 15,000,000 ° C, 27,000,000 ° F) and the pressure (340 billion times the pressure of air on Earth at sea level) is so intense that nuclear reactions are carried out. These reactions cause of four protons or hydrogen to fuse together and form an alpha particle or helium nucleus. The alpha particle has about.

7 percent less mass than the four protons. The difference in the mass is expelled as energy and is carried to the surface of the Sun, through a process known as convection, where light and heat are released. The energy generated in the center of the Sun takes a million years to reach the solar surface.

Every 700 million tons of hydrogen are converted into helium ash. In the process, 5 million tons of pure energy is released; Therefore, the sun becomes lighter every time.
