May 11, 2023 · The sun's corona can reach temperatures of around 1.8 million degrees F to 3.6 million degrees F (1 to 2 million degrees C), that's up to 500 times hotter than the photosphere.

Feb 13, 2025 · The hottest part of the Sun is its core, where temperatures top 27 million °F (15 million °C). The part of the Sun we call its surface – the photosphere – is a relatively cool 10,000 °F (5,500 °C). In one of the Sun’s biggest mysteries, the Sun’s outer atmosphere, the corona, gets hotter the farther it stretches from the surface.

Infrared radiation from the Sun is responsible for heating the Earth’s atmosphere and surface. Without energy from the Sun, Earth would freeze. There would be no winds, ocean currents, or clouds to transport water.

3 days ago · Where does the Sun's energy come from? The Sun's heat influences the environments of all the planets, dwarf planets, moons, asteroids, and comets in our solar system. How does a big ball of hydrogen create all that heat? Learn all about it in this video!

It is the hottest part of the Sun and of the Solar System. It has a density of 150,000 kg/m 3 (150 g/cm 3) at the center, and a temperature of 15 million kelvins (15 million degrees Celsius; 27 million degrees Fahrenheit). [2]

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.

Jan 2, 2024 · The Sun's radiation strikes the Earth's surface, thus warming it. As the surface's temperature rises due to conduction, heat energy is released into the atmosphere, forming a bubble of air that is warmer than the surrounding air.

Feb 2, 2024 · Without the sun’s heat and light, life on Earth would not exist. About 4.5 billion years ago, the sun began to take shape from a molecular cloud that was mainly composed of hydrogen and helium. A nearby supernova emitted a shockwave, which came in contact with the molecular cloud and energized it.

The hottest part of the Sun is its core, where temperatures top 27 million °F (15 million °C). The part of the Sun we call its surface – the photosphere – is a relatively cool 10,000 °F (5,500 °C). In one of the Sun’s biggest mysteries, the Sun’s outer atmosphere, the corona, gets hotter the farther it stretches from the surface.
