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.
On that scale with our Solar System in your hand, the Milky Way Galaxy, with its 200 â 400 billion stars, would span North America (see the illustration on the right). Galaxies come in many sizes. The Milky Way is big, but some galaxies, like our Andromeda Galaxy neighbor, are much larger. The universe is all of the galaxies â billions of them! NASAâs telescopes allow us to study galaxies beyond our own in exquisite detail, and to explore the most distant reaches of the observable universe.
