How does energy leave the sun?

Answer 1

The sun radiates energy in the visible, infra-red, and ultra-violet areas of the electromagnetic radiation spectrum. In fact the sun acts as a black body would do at about 6000 degC. On earth the infra-red radiation we receive accounts for most of the heating which keeps the earth and its atmosphere at temperatures we can live in. There is a constant interchange going on, we receive energy but also re-emit energy so that over a period our temperature remains in balance.

Answer 2

Energy leaves the sun in the form of electromagnetic radiation, such as visible light and heat. This energy is generated through nuclear fusion reactions in the sun's core, where hydrogen is converted into helium. The energy produced in the core then moves outward through the layers of the sun, eventually reaching the surface and being emitted into space.
