The sun is currently a main sequence star.
The very center of the core, where nuclear fusion is occurring is the hottest part of the sun. It's millions of degrees!
For two reasonsPlanets orbit Stars.Stars emit energy as a result of nuclear fusion reactions occurring in their cores, planets do not.The solar system's planets orbit the Sun (making the Sun a Star by criterion 1) and the Sun emits energy as a result of nuclear fusion reactions occurring in its core (making the Sun a Star by criterion 2).
In a process known as nuclear fusion, hydrogen is constantly fused into helium.
The Sun provides all of the energy we need. Without that energy, life on Earth would not exist.
The energy of the sun comes from nuclear fusion occurring in the sun's core. The moon does not have an internal energy source. What little energy falls on it comes from the sun.

Nuclear fusion: mainly of hydrogen into helium. To a lesser extent there is fusion of helium into larger elements - all the way to iron.

No, it is occurring in all stars including our sun, and we would not exist otherwise. On Earth it is still experimental
