Actually, it is not. The Sun's core is about 28,000,000°F, but it needs to be at least 100 million to undergo nuclear fusion. There are some factors that fusion can occur there. One is density and pressure. The amount of pressure overturns the weak nuclear force which is the force that resists atoms from fusing. Another process known as quantum tunneling provides a sort of "barrier" that helps overcome the weak force and helps force the atoms to fuse.
Nuclear _fusion_ occurs in the core of the Sun.
The reason the centre of the sun is 15 million C is because of the sufficient amounts of radiation in it.
The fusion of hydrogen into helium.

For nuclear fusion.
The temperature varies on different parts of the Sun. For rexample, the visible part (photosphere) has a temperature of almost 6000 degrees Celsius, while the nucleus is estimated to be 15 or 16 million degrees.
The corresponding white dwarf needs to reach a temperature for nuclear fusion to occur, which is about 20 million degrees kelvin.
Not even close. The Sun is a little (very little) bigger than average, but the "average" includes some puny stars indeed. There are stars that are up to 150 times more massive than the Sun, and hundreds of times larger in diameter, and thousands of degrees hotter. Some astronomers have observed - correctly - that the sun is about as "average" as a star gets.
at 20 million degrees fahrenheit the hydrogen within the star ignites and burns in a continuing series of nuclear reactions . the onset of these reactions marks the birth of a star

About 180 million degrees Fahrenheit upon detonation, which is some 10,000 times hotter than the surface of the sun.
10 million degrees with a football field worth of hydrogen under a lot of pressure the process is called nuclear fusion
You get Nuclear Fusion, which produces an enormous amount of energy. The center of the sun, for example, is near 20 million degrees Kelvin
Yes. The inside of the sun is hotter. The energy that powers the sun originates from nuclear fusion in its core, which is heated to about 25 million degrees. By contrast at the surface the sun has a temperature of about ten thousand degrees.
The sun is a mass, Of incandescent gas, A gigantic nuclear furnace, Where hydrogen is built Into Helium, At a temperature of millions of degrees.
Nothing, it just got a little hotter. For nuclear fusion to occur it had to reach 10 million degrees kelvin.
