WebScientists consider the “surface” of the Sun to be the region above which most photons (the quantum carriers of light energy) escape. The photosphere is thus a layer some 400 km (250 miles) thick. The temperatures in this layer range from 4,400 kelvins (K; 4,100 °C, or 7,400 °F) at the top to 10,000 K (9,700 °C, or 17,500 °F) at the bottom.
