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.
Our Sun is a fairly average star in the Main sequence: Stars range is size from white dwarfs with ca.a radius just .01 times that of our own sun, although their mass is about the same. Supergiants may have diameters several hundred times the size of our Sun. Sadly, we don't yet know the full scope of the sizes of other solar systems to compare to our own.
