The sun

The sun – the central body of the solar system – is a hot plasma ball. The sun is the star closest to Earth. The light from it reaches us in 8.3 minutes. The sun has decisively influenced the formation of all the bodies of the solar system and created the conditions that led to the emergence and development of life on Earth. Its mass is 333,000 times the mass of the Earth and 750 times the mass of all other planets combined. Over the 5 billion years of the sun’s existence, already about half of the hydrogen in its central part has turned into helium. As a result of this process, the amount of energy that the sun radiates into world space is released. The radiation power of the Sun is very large: about 3.8 * 10 20 degrees MW. An insignificant part of solar energy, about half a billionth of a billion, falls on Earth. It maintains the earth’s Continue reading
