Why Is the Sun Hot?

💡 Simple Explanation

The Sun is like the biggest bonfire ever, but it doesn't burn wood - it squishes tiny things together! Deep inside the Sun, it's so heavy and squeezed that tiny pieces called atoms get pushed together and become new atoms. This is called fusion, and it releases TONS of heat and light. It's like when you rub your hands together really fast and they get warm, but a million times stronger!
