Well, it’s really hard to know for sure. The number is different depending on which part of the Sun we’re measuring. The sunspot-facing side of the Sun is about 5,800 degrees Fahrenheit (3,030 degrees Celsius). The back side of the Sun is about 1,000 degrees Fahrenheit (540 degrees Celsius) cooler.
