The surface of the sun is … 4 answers. hydrogen atoms are combined into helium atoms inside the sun's core. Answer to: What is the approximate temperature of the sun's core? Outside the sun's core lies the radiative zone where temperatures range from 12 million degrees F (7 million degrees C) nearest the core to around 4 million degrees F (2 million degrees C) in the outer radiative zone, according to the educational website Study.com. The temperature in the photosphere varies between about 6500 K at the bottom and 4000 K at the top (11,000 and 6700 degrees F, 6200 and 3700 degrees C). The Sun's core is powered by proton-proton fusion. The actual "best" value is more like 15 million K. 6,000 K: Near the Sun’s core, the energy is mainly transported by: photons, radiation pressure, protons, convection: photons 75% H, 24% He, 1% everything else c. 40% H, 59% He, 1% everything else d. 11% H, 89% He, 1% everything else Strangely, the sun is hotter away from the surface.

The net result of the proton-proton chain of nuclear reactions is that four protons are converted into. The sun's temperature varies markedly depending on how close to the surface. With a density of 160 g/cm^3, 10 times that of lead, the core might be expected to be solid. Scientists have determined the temperature near the Earth’s centre to be 6000֯ C, 1000֯ C hotter than previously thought. Topics.
