The Sun is a star that provides light for our planet Earth. This is a lot more important than we might think because not only does this light enable us to see things and give us a nice tan in the summer, but it also enables plants to thrive and produce the oxygen that all living beings need for breathing.
But watch out, because too much of the sun's rays can be damaging. In fact, we always think that having a nice tan is the same as being healthy, and that's not true.
