The temperature of the Earth's core is not known as well as the temperature of the Sun's surface (photosphere)! Here's an exercise published by NOAA which indicates that it can take up to 50 million years for photons to travel from the core to the surface of the sun. The core of the Sun extends from the center to about 20–25% of the solar radius. However, we can infer the core temperature by applying physical We can determine that mass, volume, composition, etc. Scientists estimate the age of the Sun to be about one hundred to two hundred billion years old- about 8. How big is the core of the sun? But before you get the wrong impression, keep in mind that the core of the Sun is a broiling 15,000,000ºC. Sun: The Sun is a self-luminous ball of gas held together by its own gravity and powered by thermonuclear fusion in its core. 1) at the same temperature and density as the surface. For the sun, we know how far we want to go to get out 696,000 kilometers, at the surface can lag the production of light at the core by up to 1 million years. The sun's core is explained in this article from HowStuffWorks. 2) at the same temperature but denser than the surface. Core: the temperature at the very center of the Sun is about 27 million degrees Farenheit (F). Conditions at the Sun's core (approximately the inner 25% of its radius) are extreme. Nobody knows for sure how the Sun was formed. Do the heavier elements "sink" to the "bottom" of the core, like iron has during planetary formation? So the sun's weight equals 340,000 Earths! Learn about the sun's core and how scientists know what the sun's core is made of. So that at the center of the sun we should find a very hot core with a temperature that reaches about 27,000,000 °F (15,000,000 °C)", 15,000,000 K. The sun is about 860,000 miles in diameter.
