The Sun

Posted in Sun on February 23rd, 2008

Like a ball of fire resting up in the sky is our source of natural light.  The scientific explanation of the sun is widely accepted and understood by many. But the reality of its existence will always remain a mystery to me.

The sun is the central body of the solar system.  It provides the light and energy that sustains life on earth, and its changing position relative to the earth’s axis determines the terrestrial seasons.

The sun is a star of a type known as G2 dwarf, a sphere of hydrogen and helium 1.4 km in diameter which obtains its energy from nuclear fusion reactions deep within its interior, where the temperature is about 15 million degrees Kelvin. The surface is a little under 6,000 degrees Kelvin.
