What fuels the Sun?

Nuclear fusion is what happens in the Sun – it''s the combining of light elements into heavier elements to produce energy. The Sun produces a large amount of energy by combining very light elements such as hydrogen to heavier elements such as helium and then lithium,

About How does sun generate energy

About How does sun generate energy

The core of the sun is the region that extends from the center to about 20–25% of the solar radius. It is here, in the core, where energy is produced by hydrogen atoms (H) being converted into nuclei of heliu.

This is the zone immediately next to the core, which extends out to about 0.7 solar radii.

This is the sun's outer layer, which accounts for everything beyond 70% of the inner solar radius (or from the surface to approx. 200,000 km below). Here, the temperatur.

Lastly, there is the photosphere, the visible surface of the sun. It is here that the sunlight and heat that are radiated and convected to the surface propagate out into space. Te.The sun generates energy through nuclear fusion123. In its core, hydrogen atoms fuse together to create helium, releasing an enormous amount of energy2. This solar radiation reaches Earth and can be captured by solar technologies to create useful forms of energy45.
