HOW HOT IS THE SUN?

The Sun’s atmosphere is made of several layers, including, the corona and the chromosphere. The outer layer, the corona, extends out for thousands of miles above the surface and is in excess of 1,000,000 degrees Celsius. The chromosphere extends out for about 1,200 miles above the surface of the Sun and has a temperature that ranges from 4,000 to 6,000 degrees Celsius. At the interior of the Sun, the convective zone has a temperature of 2,000,000 Kelvin, which is about 2,000,000 degrees Celsius, while the core is the hottest region of the Sun, with temperatures here estimated to be as high as 16,000,000 Kelvin, or 16,000,000 degrees Celsius. The core has an incredible density too – around ten times that of gold.
