WebThe 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)). [1] It is the hottest part of the Sun and of the Solar System. Approximately 3.7×10 protons (hydrogen nuclei) , or roughly 600 million tonnes of hydrogen, are converted into helium nuclei every second releasing energy at a rate of 3.86×10 joules per second. The core produces almost all of the Sun's heat via fusion: the rest of the star is heated by the outward transfer of heat from the core. The energy produced b…
