What powers the Sun?

Answer 1

The sun is powered by nuclear fusion. Hydrogen is converted to helium resulting in energy and heat.

Answer 2

If you're just asking because you want to know, I'm not sure there is a "correct" answer. Stars are powered by different processes depending on where they are in their evolution, and often by more than one process at the same time (for example, it's possible for a star to get part of its power from the proton-proton chain reaction and part of it from the CNO cycle). Neither of those are, strictly speaking, "parts of atoms."

If you're asking because it's on a homework assignment, then ... the answer whoever wrote it was probably looking for is "nucleus."

Answer 3

The Sun is powered by nuclear fusion, where hydrogen atoms combine to form helium, releasing a large amount of energy in the process. This heat and light generated by nuclear fusion are what make the Sun shine and provide energy to sustain life on Earth.

Answer 4

The fusion of light nuclei, usually hydrogen, powers the sun and other stars.

Answer 5

It is actually nuclear fusion rather than "atoms"

Answer 6

fusion of hydrogen atoms into helium
