What is the temperature of the sun's surface?

The temperature of the sun's surface, also known as the photosphere, is about 5,500 degrees Celsius or 9,932 degrees Fahrenheit. This temperature varies depending on the location on the sun's surface, with some areas being slightly cooler or hotter than others.

The sun's surface is not the hottest part of the sun, as the temperature increases as you move inward toward the sun's core. The temperature at the core is estimated to be around 15 million degrees Celsius or 27 million degrees Fahrenheit. This is where nuclear fusion occurs, which is the process that powers the sun and produces light and heat.
