The sun produces energy by nuclear fusion of hydrogen into helium in its core, releasing heat and light. Learn about the sun's layers, how energy is transferred and radiated, and how it affects Earth.
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).
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 produces around 400 trillion watts of energy every day1. It releases energy at a mass-energy conversion rate of 4.26 million metric tons per second, which produces the equivalent of 384.6 septillion watts (3.846×10 26 W)2.
