THE TEMPERATURE OF THE SUN
The Sun's
core can reach 10 to 22.5 million°F. The surface temperature is approximately
9,900°F (5,500°C). The outer atmosphere of the Sun (which we can see during a
solar eclipse) gets extremely hot again, up to 1.5 to 2 million degrees. At the
center of big sunspots the temperature can be as low as 7300 °F (4300 K, 4000
°C). The temperature of the Sun is determined by measuring how much energy (both
heat and light) it emits.
