      The sun is about 5500 degrees Celsius. Remember that water boils at about 100 degrees Celsius and this is already very, very hot! So, the Sun is about 55 times hotter than boiling water.

      In it’s core, where the Sun is violently taking hydrogen atoms and by sheer gravitational force and heat, fusing them together to make helium, the temperature has been calculated to be around 15 million degrees Celsius. This bond formation, or ‘nuclear fusion’ is the source of all of the immense amount of heat, light, and other forms of radiation the Sun produces. At the surface the temperature gets quite cool, like Ross said, a brisk 5,500 degrees Celsius. 🙂

      Far too hot for humans! I am glad we are far enough away from the sun not to burn!
