Web5 jul. 2024 · Like any star in its prime, the sun consists mainly of hydrogen atoms fusing two by two into helium, unleashing immense energy in the process. But it’s the sun’s tiny concentration of heavier elements, which astronomers call metals, that controls its fate. The core of the Sun is considered to extend from the center to about 0.2 to 0.25 of solar radius (140,000–170,000 kilometres (87,000–106,000 mi)). It is the hottest part of the Sun and of the Solar System. It has a density of 150 g/cm at the center, and a temperature of 15 million kelvins (15 million degrees Celsius, 27 million degrees Fahrenheit).

Web9 apr. 2024 · Specifically, in the Sun’s core, hydrogen atoms fuse to make helium. The energy produced in the core powers the Sun and produces all the heat and light the Sun emits. Energy from the core is carried outward by radiation, which bounces around the radiative zone, taking about 170,000 years to get from the core to the top of the … WebThe energy that is emitted from the Sun is produced: D. in the core, by nuclear fusion. The proton-proton chain powers the Sun by fusing hydrogen into helium. As a by-product, several different particles are produced, which eventually produce energy. marketaxess.com zoominfo
