13 Δεκ 2023 · The hottest part of the Sun is the core: 15 million K; ~15 million °C; 27 million °F. The coolest part of the Sun is the visible surface or photosphere: 4,000 – 6,500 K; ~5,500 °C; ~10,000 °F. Surprisingly, the solar atmosphere or corona is hotter than the Sun’s surface.
17 Ιουλ 2021 · The Sun is nearly a perfect sphere of hot plasma. The average surface temperatures are at around 5.778 K, but they vary since it is composed out of three layers. Our Sun is an enormous energy and light-producing sphere of glowing gases. Though it is the hottest object in the solar system, other stars are far hotter, even tens of times so.
11 Μαΐ 2023 · The temperature of the sun varies from around 27 million degrees Fahrenheit (15 million degrees Celsius) at the core to only about 10,000 degrees F (5,500 degrees C) at the surface,...
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 )
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% ...
It is only about 500 km (300 miles) wide, a much thinner layer than the interior solar regions. The temperature of the photosphere is around 5,500 °C (9,900 °F), which is much cooler than the Sun's core. Most of the light energy produced in the Sun’s core escapes from the photosphere.
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!).
