Children's LiteratureThe Sun has always been of great interest to man. It was considered a god by many ancient peoples. We now know that our Sun is a star in the Milky Way galaxy. The Milky Way has a trillion stars. Just as the Earth orbits the Sun, the sun orbits the center of the Milky Way. That orbit takes about 200 million years. SOHO is a robot spacecraft that studies the Sun. Scientists are very interested in learning more about sunspots and how they affect us here on Earth. They may affect our weather. The Sun is very hot, the core is 28 millions degrees Fahrenheit. This heat energy takes millions of years to reach the surface of the Sun. Light from the Sun travels to the Earth in a little over eight minutes. This book is part of the "Our Galaxy and Beyond Series." These books are designed for young students who have had a basic introduction to the solar system. They present more sophisticated basic information about celestial objects and their exploration. Consequently, they are more text based with fewer photographs and illustrations than other series for younger students. Each volume includes a glossary and statistics about the size, atmosphere, orbit, length of a day and temperature range of each celestial object. 2004, The Child's World, Ages 7 to 12.
