Thousands of stars shine in the night sky, but during the day only one is visible! The Sun, the star in the center of our solar system is 93 million miles away from our Earth. Learn about the temperature, atmosphere, and composition of the Sun, as well as how the Sun's burning gases make heat and light, causing Earth's weather and climate. Bathing our planet in warmth and light, learn how plants, animals, and humans all depend on this big ball of light formed over 4 billion years ago! This book will allow students to make observations at different times of the year to relate the amount of daylight to the time of year.
