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.
The stellar disk of the Milky Way Galaxy is approximately 100,000 light-years (9Ã1017 km) (6Ã1017 mi) in diameter, and is considered to be, on average, about 1,000 light-years (9Ã1015 km) thick. It is estimated to contain at least 200 billion stars and possibly up to 400 billion. 1 person found this useful.
