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.
Thank you for your question. Our Milky Way galaxy is a pretty typical large galaxy. Most of the stars are in a disk that is about 100,000 light years across in diameter and 3000 light years thick. Most of the galaxies in the universe are actually smaller than the Milky Way.
