Characteristics of the Sun The Sun is a large star

It is about 864,000 miles (1.4 million km) wide, and is filled with scorching gases that represent more than 99.8% of the total mass in the solar system, and has a temperature of about 10,000 degrees Fahrenheit on the surface and 15.5 million degrees Celsius in the center of the Sun.

 In the center of the sun, nuclear fusion reactions take place,

Which causes the conversion of hydrogen into helium, which generates energy, and particles of light called photons carry this energy through the spherical envelope of the sun, to the upper layer of the inner part of the solar energy, which is the convection zone, and there it transfers energy to the surface, and it is worth noting that This journey takes more than a million years.

Here are some facts about the sun
