Initial Findings of Trade Smart University. After signing up for a trial account, I reviewed several of the videos and educational materials offered. The materials presented are very basic technical analysis. Nothing extraordinary.
The solar system itself is around 1.2 light years wide on the average. In AU, this is a huge number (one AU are only about 8.5 lightminutes): 75888 AU The heliopause, on the other hand, is only about 200 AU across. Lot's of stuff, which is still orbiting the sun (The Oort cloud) is outside the heliopause.
A light year is 5,865,696,000,000 miles (9,460,800,000,000 kilometers). That's a long way! Using a light year as a distance measurement has another advantage -- it helps you determine age. Let's say that a star is 1 million light years away.
