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]
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...
The core of the Sun extends from the center to about 20–25% of the solar radius. [59] It has a density of up to 150 g/cm 3 [60] [61] (about 150 times the density of water) and a temperature of close to 15.7 million kelvin (K). [61] By contrast, the Sun's surface temperature is about 5800 K.
In new research, scientists studying what the conditions at the core should be like found that the center of the Earth is way hotter than we thought—around 1,800 degrees hotter, putting the ...
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)
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.
