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.
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.
This superheated core, says the BBC, is about as hot as the surface of the Sun. Scientists know the Earth’s core, a multi-layered structure with a solid iron core spinning in a sea of liquid ...
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.
The connection and interactions between the Sun and Earth drive the seasons, ocean currents, weather, climate, radiation belts and auroras. Though it is special to us, there are billions of stars like our Sun scattered across the Milky Way galaxy.
22 Σεπ 2022 · The temperature at the very center of the Sun is about 15,000,000° C (27,000,000° F) and the density is about 150 g/cm³ (approximately 10 times the density of gold, 19.3 g/cm³ or lead, 11.3 g/cm³). Both the temperature and the density decrease as one moves outward from the center of the Sun.
