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% ...
17 Ιουλ 2021 · The Sun is nearly a perfect sphere of hot plasma. The average surface temperatures are at around 5.778 K. Click for even more facts and information.
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.
Model values at center of Sun: Central pressure: 2.477 x 10 11 bar (2.477 x 10 17 g/cm s 2 ) Central temperature: 1.571 x 10 7 K Central density: 1.622 x 10 5 kg/m 3 (1.622 x 10 2 g/cm 3 )
13 Δεκ 2023 · Learn about the Sun's temperature variations, from 15 million K in the core to 5,500 K in the photosphere. Find out how scientists measure the Sun's temperature and compare it with other stars and Earth's extremes.
The Sun is extremely hot! The center of the Sun is at least 10 million degrees. The “surface” of the Sun (what we see) is only 5800 degrees Kelvin (~10,000 Fahrenheit) This is cool for the Sun, but is actually about 16 times hotter than boiling water (ouch!).
