What is the temperature of the Sun?
The temperature of the sun varies from around 27 million degrees Fahrenheit (15 million degrees Celsius) at the core to only about 10,000 degrees F (5,500 degrees C) at the surface, according to NASA. Every 1.5 millionths of a second, the sun releases more energy than all humans consume in an entire year according to NASA Space Place.

What is the temperature of the Sun's core?
In the Sun’s core, gravitational attraction produces immense pressure and temperature. Some estimates put the temperatures at 27 million degrees Fahrenheit / 15 million degrees Celsius. The process of nuclear fusion occurs when hydrogen atoms are compressed and fused together, creating helium.

What is the hottest part of the Sun?
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.

How does the temperature of the Sun vary?
Arranged in layers, the sun varies in temperature: It is hottest at its center, and cooler in its outer layers — until it strangely reheats at the fringes of the sun's atmosphere. At the sun's core, gravity causes intense pressure, and temperatures of up to 27 million degrees Fahrenheit (15 million degrees Celsius).

Which part of the Sun is hotter than the surface?
Surprisingly, the solar atmosphere or corona is hotter than the Sun’s surface. Also, the temperature is quite variable: 500,000 – 2,000,000 K; ~2 million ° C; ~ 3.5 million ° F. The core, where nuclear fusion occurs, is the hottest part of the Sun. Here, hydrogen atoms fuse to form helium, releasing immense energy.

What is the temperature of the photosphere?
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 light. Sunspots on the photosphere appear dark because they are cooler than the other parts of the sun's surface.
