How hot is the Sun?

The Sun is the star at the center of our solar system. The Sun’s temperature varies across regions, including its core, photosphere, and corona. The Sun’s surface, known as the photosphere, exhibits a temperature range. Learn about the Sun’s temperature measurements in both Fahrenheit and Celsius scales. The Sun’s heat influences the entire solar system and plays a crucial role in supporting life on Earth.

The Sun’s temperature varies across its layers. The Sun’s core reaches 27 million degrees Fahrenheit or 15 million degrees Celsius. The photosphere, which is the Sun’s surface, maintains a temperature of 10,000 degrees Fahrenheit or 5,500 degrees Celsius. Temperature variations exist within the photosphere itself, ranging from 7,460°F (4,125°C) at the top to 10,000°F (5,540°C) at the bottom.

The Sun’s maximum temperature is found in its core. Nuclear fusion reactions in the core generate heat, with temperatures estimated at 27,000,000°F (15,000,000°C). Pressure and density cause the core’s higher temperature compared to other regions of the Sun. Temperature decreases from the core outward through the radiative and convective zones.

The Sun’s corona, its outer atmosphere, exhibits high temperatures. Corona temperatures range from 1.8 million to 3.6 million degrees Fahrenheit (1 million to 2 million degrees Celsius).
