The Sun and the stars Characteristics of the Sun Our Sun is an ordinary star — 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. 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.

Project Solar energy collection is most effective in areas that receive direct sunlight for long periods of time. Research areas on Earth that receive direct sunlight Critique different zones of the Earth. Evaluate the data and make a recommendation (using the scientific data) to locate a solar energy facility. Share and defend the recommendation with the class.
