Top 7 Common Sun Facts Everyone Must Know

Since its creation, the sun has used up about half of the hydrogen in its core

The sun’s energy output is 386 billion billion megawatt. The Earth receives 94 billion megawatt of energy from sun. This is equivalent to 40,000 times the power requirement of United states. The reaction taking place in sun is nuclear fusion, same as a Hydrogen bomb. Each second 700 million tons of Hydrogen are converted to 695 million tons of Helium and 5 million tons of energy in the form of gamma rays. Each second the sun loses 5 million tons of material.

The Sun generates this huge amounts of energy by combining hydrogen nuclei into helium through the process of nuclear fusion. Over the next 5 billion years or so, it will grow steadily brighter as more helium accumulates in its core. As the supply of hydrogen dwindles, the Sun’s core must keep producing enough pressure to keep the Sun from collapsing in on itself. The only way it can do this is to increase its temperature. Eventually it will run out of hydrogen fuel. At that point, it will go through a radical change which will most likely result in the complete destruction of the planet Earth.
