Change Author / Owner : Chapter 3: The Sun (in AUDIO ONLY)
The star that dominates our daytime sky and provides the heat and light to support life on Earth is, of course, the Sun. In astronomical terms it is very close, 150 million kilometers (93 million miles), so we can study its properties in great detail. Light from the Sun takes just over eight minutes to reach the Earth. For comparison, light from the next nearest star takes four years to reach us.
