The core is the hottest part of the Sun. Nuclear reactions here – where hydrogen is fused to form helium – power the Sun’s heat and light. Temperatures top 27 million °F (15 million °C) and it’s about 86,000 miles (138,000 kilometers) thick. The density of the Sun’s core is about 150 grams per cubic centimeter (g/cm³).
Dec 13, 2023 · Learn about the temperature of the Sun's different layers, from the core to the corona, and how it varies. Find out how scientists measure the Sun's temperature and how it compares with other stars and Earth's extremes.
Jul 17, 2021 · The Sun is nearly a perfect sphere of hot plasma. The average surface temperatures are at around 5.778 K, but they vary since it is composed out of three layers. Our Sun is an enormous energy and light-producing sphere of glowing gases. Though it is the hottest object in the solar system, other stars are far hotter, even tens of times so.

Why is the Sun's corona so much hotter than the Sun's surface? (more unsolved problems in astronomy) The temperature of the photosphere is approximately 6,000 K, whereas the temperature of the corona reaches 1,000,000–2,000,000 K. The high temperature of the corona shows that it is heated by something other than direct heat conduction from the photosphere. It is thought that the energy ...
