Why do we call it the solar system? At its centre, the sun is the closest star to earth. It provides the Earth with the heat and light that makes life on Earth possible. Find out what the sun is all about, how big it is, what it's made of, how old it is and perhaps most importantly, how long it will continue to burn. Includes a hands-on activity ideal for science fair project ideas.
