The sun

      Planets orbit the sun in a oval shape.  The suns surface is 6000 degrees Celsius.  Our sun is a average size star.  The suns life span is 10 billion years.  The sun started out as a cloud of gas.  The sun is a gigantic ball of gasses.  The sun gives out tremendous amounts of energy and heat.  When the sun runs out of hydrogen fuel it will turn into a red giant.   The red giant will go to a supernova or a white dwarf.  The largest supernovas are turned into a neutron star.  A black hole is the last stage in a suns life.
