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.
The Sun is gradually becoming hotter in its core, hotter at the surface, larger in radius, and more luminous during its time on the main sequence: since the beginning of its main sequence life, it has expanded in radius by 15% and the surface has increased in temperature from 5,620 K (9,660 °F) to 5,772 K (9,930 °F), resulting in a 48% ...
In the center, the core of the Sun is around 15,000,000°C (27,000,000°F). Most of the "surface" of the Sun (AKA the photosphere) is a lot cooler—around 5,500°C (10,000°F). Sunspots can be a little less hot, around 4,000°C (7,300°F).
The temperature in the Sun's core is about 27 million degrees Fahrenheit (15 million degrees Celsius) – hot enough to sustain nuclear fusion. This creates outward pressure that supports the star's gigantic mass, keeping it from collapsing.
How do we know the temperature at the centre of the Sun? - BBC Science Focus Magazine.
The temperature at the surface of the Sun is about 10,000 Fahrenheit (5,600 Celsius). The temperature rises from the surface of the Sun inward towards the very hot center of the Sun where it reaches about 27,000,000 Fahrenheit (15,000,000 Celsius).
