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 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.
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 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% ...
The core of the Sun is considered to extend from the center to about 0.2 of the solar radius (139,000 km; 86,000 mi). [1] It is the hottest part of the Sun and of the Solar System. It has a density of 150,000 kg/m 3 (150 g/cm 3) at the center, and a temperature of 15 million kelvins (15 million degrees Celsius; 27 million degrees Fahrenheit). [2]
16 lis 2023 · Even though it’s sitting right next to the Sun – relatively speaking – Mercury gets extremely cold at night. It has a mean surface temperature of 333°F (167°C). Daytime temperatures get much hotter than the mean, and can reach highs of 800°F (430°C).
