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.
At its largest point, this galaxy extends about 2 million light-years from its core, and it has a mass of about 100 trillion stars (some estimates suggest that it is 6 million light-years in diameter). To give you some idea of what this means, the Milky Way is just 100,000 light-years in diameter.
