    13 gru 2023 · From the fiery depths of its core to the outermost reaches of its corona, here are the temperatures, from millions of degrees in Kelvin to the more comprehensible Celsius and Fahrenheit scales. The hottest part of the Sun is the core: 15 million K; ~15 million ° C; 27 million ° F.
