2. The sun is a star

What we call the sun is a star, one of many billions in our galaxy. The Latin scientific name for the sun is Sol – but most texts call it the Sun. The energy our sun gives out is what allows life to exist on Earth. This energy takes the form of radiation we cannot see, such as heat, and light energy we can see. Although the sun is 92.96 million miles away from the Earth, we get just the right amount of light for life to thrive. If our planet were closer like Venus or further away like Mars, the light we received would be too much or little to support life.
