The temperature on the Sun isn't a single, uniform number. It varies greatly depending on where you are on the Sun:

* Core: The hottest part of the Sun, where nuclear fusion takes place. It reaches a staggering 15 million degrees Celsius (27 million degrees Fahrenheit).

* Photosphere: The visible surface of the Sun. This is the layer we see from Earth. The temperature here is around 5,500 degrees Celsius (9,932 degrees Fahrenheit).

* Chromosphere: The layer above the photosphere. This is a thin layer with temperatures ranging from 4,000 to 100,000 degrees Celsius (7,232 to 180,000 degrees Fahrenheit).

* Corona: The outermost layer of the Sun's atmosphere. This is a very hot and diffuse region with temperatures reaching millions of degrees Celsius (millions of degrees Fahrenheit).

So, while the temperature on the Sun's surface is around 5,500 degrees Celsius, it can get much hotter in other parts of the Sun.
