Detailed explanation-1: -The hottest part of the Sun is its core, where temperatures top 27 million degrees Fahrenheit (15 million degrees Celsius).
Detailed explanation-2: -The hottest part of our Sun is its core, where nuclear fusion reactions create temperatures up to 15 million degrees Celsius (ºC) or 27 million degrees Fahrenheit (ºF), according to NASA.
Detailed explanation-3: -The Sun is a bit more complicated. The heat in the Sun is caused by nuclear fusion of the hydrogen it contains, which happens because of the extreme pressure and temperature at its center, where the temperature is around 15, 000, 000 K (15 million K or 27 million ºF).
Detailed explanation-4: -The core of the Sun is considered to extend from the center to about 0.2 to 0.25 of solar radius (140, 000–170, 000 kilometres (87, 000–106, 000 mi)). It is the hottest part of the Sun and of the Solar System.
Detailed explanation-5: -Eta Carinae could be as large as 180 times the radius of the Sun, and its surface temperature is 36, 000-40, 000 Kelvin. Just for comparison, 40, 000 Kelvin is about 72, 000 degrees F. So it’s the blue hypergiants, like Eta Carinae, which are probably the hottest stars in the Universe.
