Where Does The Sun Get Its Energy?

The Sun gets its energy from a giant, nonstop burning inside it, like a supercharged campfire that never goes out.

Imagine you have a big pile of logs, and every time you light one on fire, it burns really hot. Now imagine that pile is huge, so huge, it fills the whole sky! That’s kind of what the Sun is like. Inside it, hydrogen (a tiny atom) collides with hydrogen and turns into helium, letting out a bunch of energy in the form of heat and light.

This burning has been going on for billions of years, and it will keep going for billions more. It’s like having a super-powered toaster that never stops toasting, but instead keeps making bread (or energy) forever. The Sun is just really, really good at burning, and that's where all its energy comes from.
