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.

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, according...
13 Δεκ 2023 · 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. Also, the temperature is quite variable: 500,000 – 2,000,000 K; ~2 million ° C; ~ 3.5 million ° F.
How do we know the temperature at the centre of the Sun? - BBC Science Focus Magazine.
Sun Fact Sheet. Sun/Earth Comparison. Bulk parameters. 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) Rotational and Orbital parameters.
29 Ιουλ 2023 · The typical temperature at the center of a large sunspot is about 3800 K, whereas the photosphere has a temperature of about 5800 K. (credit: modification of work by NASA/SDO) As we saw, the energy that emerges from the photosphere was originally generated deep inside the Sun (more on this in The Sun: A Nuclear Powerhouse).
15 Ιαν 2014 · Arranged in layers, the sun varies in temperature: It is hottest at its center, and cooler in its outer layers — until it strangely reheats at the fringes of the sun's atmosphere.
