Teach Astronomy - Astronomical Units
http://www.teachastronomy.com/ The astronomical unit is defined as the mean distance between the Earth and the Sun. It has to be defined as the mean because the orbit is elliptical by a couple of percent. The astronomical unit is 150 million kilometers or 98 million miles. This sets the

How Far Is Earth From the Sun?
It's amazing to think that for the majority of human history, we had almost no understanding about the Sun. We didn't know what it was made of, how it formed, or how it produced energy. We didn't know how big it was, and we didn't know how far away it was. We orbit the Sun at a distan
