Full Answer

The surface of the sun is actually the coolest part of the sun, with an average temperature of about 10,000 degrees Fahrenheit. Sunspots on the surface are believed to be even cooler, at about 8,000 degrees. The corona, located above the surface of the sun, reaches temperatures of almost 1,000,000 degrees. The core of the sun is the hottest part of the sun by far, with nuclear fusion producing temperatures in excess of 25,000,000 degrees. The sun is a relatively cool star, however, with some stars reaching stable temperatures of 200,000,000 degrees and supernova temperatures of up to 10,000,000,000 degrees.
