Présentation de l'éditeur
The sun is a star, like billions of others. But it is the star that is closest to us. It keeps us warm and gives us light and energy. Without the sun, there would be no life on Earth.
Read and find out what the sun is made of. Find out how hot it is, how far away it is, and how long it takes for its light to reach Earth. And try an experiment that will show you how sunlight helps plants grow.
