May 11, 2023 · In the photosphere, temperatures reach about 10,000 degrees F (5,500 degrees C) according to the educational website The Sun Today. It is here that the sun's radiation is detected as visible...

The Sun is the star at the centre of the Solar System. It is a massive, nearly perfect sphere of hot plasma, heated to incandescence by nuclear fusion reactions in its core, radiating the energy from its surface mainly as visible light and infrared radiation with 10% at ultraviolet energies.

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.

Jan 14, 2025 · The Sun contains almost ALL of the material in our solar system. 99% of it. All the planets, asteroids and comets add up to less than 1% of the total. The Sun is so far away that it takes light about 8 minutes and 20 seconds for it to get …

Dec 13, 2023 · The hottest part of the Sun is the core: 15 million K; ~15 million °C; 27 million °F. The coolest part of the Sun is the visible surface or photosphere: 4,000 – 6,500 K; ~5,500 °C; ~10,000 °F. Surprisingly, the solar atmosphere or corona is hotter than the Sun’s surface.

Feb 13, 2025 · The temperature in the Sun's core is about 27 million degrees Fahrenheit (15 million degrees Celsius) – hot enough to sustain nuclear fusion. This creates outward pressure that supports the star's gigantic mass, keeping it from collapsing.

Mar 11, 2025 · The average temperature of planet Earth is 59°Fahrenheit, which is 15°Celsius. As a rule, the surface temperature of a planet depends on how far it is from the sun. By this rule, Mercury should be the hottest planet in the solar system. Surprisingly, it is not. Instead, Venus is the hottest planet in the solar system.

Apr 14, 2024 · How Hot Is The Sun? The great ball of fire in the sky (or rather, plasma, to be exact) holds the solar system together and provides the heat, energy, and illumination necessary to sustain life on Earth. And yet, the Sun itself is the most overwhelmingly inhospitable environment imaginable. Its core burns hot enough to sustain nuclear fusion ...

Apr 11, 2023 · The Sun has varying temperatures depending on the layer. Here is how hot the Sun's surface, core and corona are, plus how nuclear fusion works.

The temperature at the surface of the Sun is about 10,000 Fahrenheit (5,600 Celsius). The temperature rises from the surface of the Sun inward towards the very hot center of the Sun where it reaches about 27,000,000 Fahrenheit (15,000,000 Celsius). The temperature of the Sun also rises from the surface outward into the Solar atmosphere.
