The Sun

The sun is one of the most remarkable and important components in our solar system.  Distributing heat from millions of miles away to the earth is only possible by the process that happens within the core of the sun.  Nuclear fusion, or collision of hydrogen nuclei to form helium nucleus that produces light, happens at 10 million kelvin, but the core of the sun is thought to be even hotter at 15 million kelvin.  The sun is estimated to be 4.6 billion years old and will continue to create light for another 5.4 billion years.  The sun is actually getting smaller because of nuclear fusion.  Nuclear Fusion takes 4 hydrogen nuclei to create 1 Helium nucleus and thus is losing mass.  The sun contains many different layers.  The different layers from the center out are 1) the Core, 2) Radiation Zone, 3) Convention Zone, and 4) Photosphere.  The different atmospheres from closest to the sun’s surface out are the Chromosphere, Corona, and Solar Winds.  The sun is so big that 1.3 million earths can fit inside of it.  What I mentioned is only a brief summary of the endless possibilities the sun possesses.
