The core of the Sun is the only part of the Sun (and all stars) that is compressed by gravity enough to maintain runaway thermonuclear reactions to counterbalance the star's own gravity.
because it is bright!
The core just means the centre. Therefore, the core of the Sun is in the centre of the Sun.
the sun's core is the hottest part of the sun
If you are asking where does solar nuclear fusion take place, then that would be at the core of stars.
The core of the sun is where nuclear fusion occurs, producing the majority of the sun's heat and light. This fusion process converts hydrogen into helium, releasing energy in the form of heat and light.
The core of the sun is about 15 million Kelvin.
There's hydrogen at the core of the sun - that's the sun's main fuel - but earth's core is mostly iron and nickel.
Nuclear fusion. We call the activity stellar nucleosynthesis. The proton-proton chain results in the fusion of helium from the hydrogen that makes up most of the sun. A link is provided to the Wikipedia articles on the sun (specifically its core) and on the proton-proton chain.
No it is not, however it is similar to that of the sun's surface
2,798,000,000 miles (4,503,000,000 km). Although the orbit isn't perfect so these numbers are an average.
The sun will eventually run out hydrogen at its core, which is the source of energy, so it will die, but it will not explode.
The sun is millions of degrees hotter than the earths core! (:
