(EMS) The Sun Lesson

The Sun 

The sun, our star, is at the center of the solar system. We need its warmth and light to survive. Without the energy supplied by the sun, Earth would be a cold and inhospitable planet. Our world would have no liquid water, no weather, and no life. The sun's light is not the only reason we should be thankful. It's gravity also holds our solar system together. Watch the presentation below to learn more about the sun.

Characteristics of the Sun

Our sun is an ordinary star. It is just one of billions of stars in our galaxy alone. However, as our own star, the sun holds special status for us and is essential to our existence. As stated before, the sun's gravity holds the solar system together, and nuclear fusion within the sun supplies the energy for life on Earth. Without the sun, Earth would be a drastically different place. In this video segment adapted from NASA, learn some basic facts about our sun.
